⭐️⭐️⭐️
Format: Kindle
Jodi Dillon, Julian Hollister, Lucy Reed, Paige Montgomery, and the infamous Zach Thrasher make up the elite friend group, The Thrashers, at New Helvetia High School. Once Emily Mills dies on prom night, the Thrashers are under investigation for her death.
If you enjoyed Pretty Little Liars, 13 Reasons Why or One Tree Hill this is a book I would recommend to you! You will get mysterious text messages, Emily Mills’ journal and characters that reminded me of Lucas/Nathan.

Great YA thriller
Format: Kindle
(4.5⭐️)
This just might be my favorite YA thriller to date.
Julie Soto just doesn’t miss and I wouldn’t even be mad if this book got a sequel.
That epilogue- WOW! Absolutely did not see it coming and I absolutely need more.
This one definitely gives Pretty Little Liars vibes and as someone who was obsessed with that show, it really kept me engaged throughout the whole book.
The paranormal activities intertwined made it nearly impossible to want to put this down.
Each character’s complexity was perfect for the story. They all had their own secrets and it made the drama SO GOOD.
Plus a little slow burn romance mixed in as well? Perfect. I was eating it up.
I absolutely recommend picking this up ASAP.

Addictive and Fun!
Format: Kindle
This book was so addictive! I started it and finished in the same day because I didn’t want to stop reading.
This was giving Pretty Little Liars vibes but all the best parts of that show and not the eye rolling parts 😜
I genuinely think it’s worth the high praise it’s been getting. One of the ways I know I am really loving a thriller type book is when I’m having so much fun while reading it that I’m not trying to figure out how it will end. This was that for me. The pace was perfect and everyone was so interesting that I was just along for the ride. I really enjoyed the ending as well.
This was a great read.
I honestly loved it.
🎧
The audiobook was very good as well. The narrators gave each person a distinct difference so you could always tell who was talking during the dialogue scenes. I loved the audio and highly recommend it!

Mysterious
Format: Kindle
Young adult usually isn't what I like to read. This book was very well done though. It was interesting to watch and learn the secrets of all the different characters. The book starts and ends with a bang. Very well done. I really enjoyed this story
