This one really got me hooked. I can finish this book in one or two sitting if I wasn't on medications (I'm in antihistamine because of my itchy throat).
It is my first time to read a book with interchanging POVs of two main characters and it was like watching a tennis game for me.
A gripping mystery novel with sci-fi and YA as its platform. I'd definitely read the other books because a lot of questions were left unanswered and there's a lot more mysteries to be unraveled.
