Three Truths and a Lie by Brent Hartinger
Rob, Liam, Mia and Galen take a trip away for the weekend to Mia's family cabin in the middle of some deserted woods in order to get to know each other better, relax and have fun.
This psychological thriller is a great addition to a genre that is seriously lacking within the YA field. From the beginning, we're given subtle hints to each character that lays doubt in our minds before anything suspicious even happens. I loved the writing style, the characters and the twists that kept me gasping until the very end. I would highly highly recommend reading this book - if you do, let me know your thoughts!
