I've not found two characters this annoying in a long time. I'm not sure if it was the writing, the voice over, or a mix of both but somehow the tone of the whole book just felt insufferable. Nobody can be that earnest and wistful for 24 hours straight. The voices of the two main characters were just too sincere all the way through for me to enjoy this. 

Also, the author seems to have forgotten what "show don't tell" means. Never heard more monologues in my life - "I am feeling this way because my parents died and I don't want more people to die and I am sad now and I want to do this." It's a boring way to write and I ended up rolling my eyes often when listening to the characters drone on. 

I would not recommend this book. The original was much better, and I didn't even love that one. There's not much that is too different about this story to the original (still two boys who find each other and at least one is a decker and surprise surprise

they fall in love by the end

).

Save your time, find another book.
