Over stad en platteland, over stok en steen – met "Sean Y." geen probleem!
De tijdloze, eenvoudige "Sean Y." is een echte alleskunner onder de lederen zadels. Of het nu gaat om snelle ritjes in de stad, lange tochten of zelfs bikepacking-avonturen – dit zadel kan alles aan! De stevige kunststof schaal, bekleed met hoogwaardig buffelleer, maakt het bijzonder licht en daarmee de perfecte metgezel voor racefietsen, fixies, citycruisers, MTB's en trekkingfietsen. "Sean Y." is een echte blikvanger en overtuigt door zijn comfort en duurzaamheid.
Op het zadel, klaar, af!
"Sean Y." is gemaakt van supersterk en toch zacht buffelleer en is daardoor – in tegenstelling tot zadels van andere materialen – 100% ademend. Dat betekent voor jou: geen zweten, geen schuren, geen huidirritaties, zelfs niet tijdens lange afstanden. Bovendien behoort materiaalmoeheid, zoals vaak voorkomt bij PVC-zadels, met "Sean Y." tot het verleden. Dankzij de sportieve, smalle vorm en de ergonomisch gevormde zitting biedt dit zadel een dynamische en comfortabele rijervaring – en dat zonder langdurig inrijden. Dus, stap na de montage direct op je fiets en geniet van elke rit!

A Brilliant, Emotional, and Unforgettable Sci-Fi Adventure
Format: Paperback
Project Hail Mary by Andy Weir is one of those rare novels that delivers everything you could want from science fiction: gripping suspense, fascinating science, humor, heart, and a genuinely moving story about survival and friendship.
The novel follows Ryland Grace, a middle school science teacher who wakes up alone on a spacecraft with no memory of who he is or why he’s there. As his memories slowly return, the stakes become clear: humanity is facing extinction, and he may be the only person who can stop it. The mystery unfolds at a perfect pace, blending high tension with moments of discovery that keep you turning the pages.
What makes this book stand out is how seamlessly it combines hard science with accessibility. Like the author’s earlier work, the scientific details feel authentic and well researched, but they never overwhelm the story. Instead, the problem-solving becomes the engine of the plot. Each obstacle feels real, and the solutions are both clever and satisfying.
The biggest surprise—and the emotional core of the novel—is the relationship that develops during the mission. Without giving anything away, it adds warmth, humor, and depth that elevate the story far beyond a typical survival thriller. By the end, the novel becomes less about science and more about courage, trust, and the willingness to sacrifice for others.
The pacing is excellent throughout, with a balance of suspense, humor, and heartfelt moments. If there’s a small drawback, it’s that some plot developments feel a bit convenient. But the strong characters and emotional payoff more than make up for it.
Overall, this is a must-read for fans of science fiction, space exploration, and anyone who enjoys smart, character-driven storytelling. It’s thrilling, funny, deeply human, and surprisingly emotional. I finished it feeling both entertained and uplifted. Highly recommended.

Proof that lightning strikes twice ... Weir has done it again!
Format: Hardcover
According to a 2003 article on the NASA website, "NASA-funded scientists have recently learned that cloud-to-ground lightning frequently strikes the ground in two or more places ..." and that the third and fourth strokes of a lightning flash will follow the same path as the second stroke. In other words, lightning DOES strike the same place twice.
But you don't need to search the web for this information. If you want proof that lightning strikes twice, just read Andy Weir's newest book, Project Hail Mary, and you'll see that Weir has created a giant sci-fi bestseller, in the same electric path as The Martian.
Ryland Grace has a puzzle on his hands. He wakes up without a clue as to where he is, but he seems to be alone except for a computer AI that was keeping him alive. Unfortunately it didn't seem to be doing the same for two others in his ... wherever he is ... as he notes the decayed corpses in their creches on the ... well, it's a ship. A space ship. And bit by bit Grace puts the pieces of the puzzle together.
An alien microbe has been discovered. Ryland Grace is brought on to the science team to learn more about the life form because Grace, currently a middle school science teacher, wrote papers about the notation that there does not need to be water to create life. Only in a biozone such as Earth's would water be needed, but other building blocks could be used in other systems.
The science community as a whole mocked Grace, which is why he left and went on to teach kids, but now, he may be the best suited to understand this new life form. And as he remembers more and more, he also remembers that this life form is feeding on the energy output of the sun, which is decreasing the energy that gets to Earth, which spells disaster - as in the end of all life as currently known - on Earth if something isn't done.
Scientists discover that Sol isn't the only star that is losing its energy output - likely due to the alien consumption, but that there is one star, in the center of all the known stars losing their energy, that remains constant with its output. In which case, the answer to the survival for Earth is likely found there, at Tau Ceti.
The world's best scientific minds come together (by force and coercion) to create a ship that can get to Tau Ceti in twelve years (using the alien microbe as fuel) with shuttle pods to bring back answers to how to save the planet, but for the crew, it's a one-way trip.
Knowing why he's there is only the first puzzle for Grace. Now he has to figure out how to save Earth. There's a very small window of time for him to discover the way to save the human race and get the answers sent back. Take too long and the shuttles will return to a dead planet.
This book is amazing.
Author Andy Weir brings us back to the magic that made The Martian so successful - an abandoned scientist trying to survive. But Ryland Grace's story is more complicated because he's not just trying to survive, but also help humanity survive.
There's lots and lots of science - which is part of Weir's writing signature - and there's also a really wonderful story.
It's hard for me to tell you just what I liked about this book because anything I write will be a spoiler and a huge part of the joy in this book is making the discoveries with Ryland Grace.
Grace is our main character, but through the liberal use of flashbacks, we have a full cast of characters - at least one quite important to the story. Everyone is unique and individual which makes it easy to read, but just as with The Martian, where Mark Watney's personality carries the story, Ryland Grace here is the smart-mouth, sometimes funny, obsessed scientist infusing his personal tastes into his discoveries. He's also quite smart - which is good since he will need his intellect to save all of humanity.
This is a page-turner. I did not want to put this book down. Neither did my 21 year old son who picked up my copy after I was well into it and finished it before I did. And days later he's still talking about how much he liked it and quoting sections of it to me at the dinner table.
I hope Ballantine Books will do a very large print run because this is going to be huge seller and you definitely don't want to miss out on the biggest thing to come out in 2021.
Looking for a good book? Project Hail Mary by Andy Weir is proof that lightning strikes twice as this has all the excitement and energy of Weir's debut novel, with a more complicated storyline that will hold the reader all the way to the end.

Excellent Hard Sci-Fi… Until the Politics Pull You Out
Format: Kindle
I was really excited to dive into Project Hail Mary. As a longtime Isaac Asimov fan, I’ve been craving fresh, modern hard science fiction that actually respects the science. This book delivered — at least for a while.
The author injects real science into the story in a way that’s both fun and fantastic. You don’t need to be an engineer to follow it; a solid high-school education is plenty. The concepts stretch your imagination without ever feeling impossible, and for the first chunk of the book I was hooked. I genuinely thought I’d found a new favorite author.
Then the jarring interruptions started.
Out of nowhere you get yanked out of the immersive sci-fi world by modern political pandering that feels completely unnecessary. A random parenthetical about Columbus “discovering an already inhabited world” when comparing something to the New World. Casual pronoun lectures. Characters selected or described by race and identity in ways that scream “check the boxes.” These moments don’t serve the story — they feel injected. Once you notice the author’s leanings, it becomes hard to unsee.
Each time it happens, the fantasy evaporates. It takes several chapters to sink back into the story… only for the next micro-lecture to pull you right back out.
Overall, I loved the writing, the hard science, and the imagination. It’s some of the best sci-fi I’ve read in years. I just wish the author had trusted the story instead of sneaking in real-world politics. It’s like eating the best meal of your life… and then finding a hair or two in it.
Strongly recommended for the sci-fi, with the above caveat.

Main Characters: Huntyr and Wolf
•
I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆
We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger!

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟
This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens.
The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him.
I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure.
My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times.
Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!
