It was the description of 'John Green meets Rainbow Rowell' that did it for me, loath as I am to admit it, because I usually pick books to read because of their synopsis and not because of the bold headlines comparing them to this or that author. Still, I really like John Green, I adore Rainbow Rowell, and the synopsis looked like something I'd like, so I gave Our Chemical Hearts a shot. 
 It's been a while since I last went so quickly through a book, which is part of the reason for the 5* rating. I wasn't bored even once. There wasn't a moment I didn't feel like continuing to read. I did what I had to do - eat, sleep, work - and in between, I spent every free moment reading on, anxious to know what happened to Grace, what Henry would do next, how Murray and Lola would help him, what the ending would be like. This is a love story, but unlike any other I've read. The Goodreads synopsis said 'And yet, this isn't your average story of boy meets girl', which made me feel sceptical at first because they all say that, but... well, it really isn't. I'll leave you to find out for yourself what it is instead, but I know my faith in YA love stories has been restored somewhat by Our Chemical Hearts.
