I absolutely loved this, it was so well written and designed. The mixed-media content of the book really added interest to the reading experience. I loved the two main characters, they were so well written, the interactions and dialogue were great. Considering this is a young adult thriller I didn't feel it was too young, or too short or too simple. It has a cross-generational appeal. It's an absolute page-turner and it took me no time to get through the 400+ pages, it's so well paced. It has great red herrings and little clues that get your brain thinking ahead, without them being too ridiculous or too obvious.
