Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy--or could it really be possible to travel through time or take shortcuts between stars? Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space--and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible--killing your own grandfather is only one of them Written with a light touch and an irrepressible love of the fun of sci-fi scenarios--but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.Binding Type: Paperback

A beautiful story of difficult times to be who you truly were!
Format: Kindle
”She felt as if she had finally cracked the last part of a code she had been puzzling over for so long that she couldn’t remember when she had started deciphering it. She felt exhilarated."
Meet seventeen year old Lily Hu, who lives in San Francisco in the 1950’s. She is Chinese American and dreams of going to college and working with her Aunt at the Jet Propulsion Laboratory, to assist with getting a rocket into space. Her and her friend Kathleen Miller, aka Kath, are the only two girls in their advanced math class. Kath dreams of becoming a pilot one day.
Over time, Lily finds ads in magazines of male impersonators and is fascinated. The ad slips out of one of her books one day while she is in the bathroom, and her classmate Kath finds it. She tells her that she has seen the male impersonator in the ad before, Tommy Andrews, at the Telegraph Club. She tells Lily she can take her if she wants to go and Lily agrees. She wants to explore the feelings she has that she cannot quite explain yet. Over time, Lily’s feelings for Kath change from that of a friendship to something much more.
Malinda Lo did an unquestionably, fantastic job with this YA historical fiction LGBTQ novel. She touched on a subject that many authors have not written about; being an Asian American teen that identifies as a lesbian in the 1950’s. This was during a time when being gay was considered illegal, where there could be no public affection shown between members of the same sex, and when gay members could not congregate in bars/clubs. It was also during a time when the government was looking for communists. One wrong move, and Lily and her family could potentially be deported just based off of who they socialized with. Lo did her research and it shows. I especially appreciated the “Author’s Notes” section at the end of the book which gave additional information and pictures. I believe this would be a great read for younger members of the LGBTQ community.
My only critiques would be that towards the middle of the book it felt a tad slow. I also wished there was more information on how Lily and Kath’s relationship turned out. In the epilogue, their relationship status is left open and I wished I knew more about what the future held for them.

Great way to introduce children to drag queens and gender transition
Format: Paperback
This is a nice story about a little girl (in 5th grade) who lives with her mom and uncle who is a drag queen. Over the course of the story, she realizes that the reason she doesn’t like make-up, jewelry, dresses, and nail polish is NOT because she has watched a grown man wear those things her entire life. And it isn’t because some girls just don’t like those things. It is because she is really a boy. She transitions to a boy and is finally happy. This is a great story to introduce children to drag queens and the idea that if they aren’t stereotypical girls or boys, they might be born in the wrong body. Happiness can be found living a life pretending to be the sex that you are not.
