I really loved this book. The premise is terrifying: there's two months left until the world basically explodes. What do you do with the time you have left? And yet the author delivered this story in such a casual yet poignant way that I was hooked from the very beginning. Focusing on the lives of these four teens that couldn't be more different was really wonderful;it was like a modern Breakfast Club meets the end of the world. The characters each shined through the pages, and I formed a connection with them. I cared when things happened to them and I wanted things to work out for each of them until the very end. I really liked the lessons learned by each of the characters. It was sobering and allowed me to reflect on things myself. I would consider this mandatory reading, especially for teenagers. I have three quotes that I absolutely loved from this book that I think sums it up better than I can: 
 "Why had he assumed time was some sort of infinite resource? Now the hourglass had busted open, and what he'd always assumed was just a bunch of sand turned out to be a million tiny diamonds." 
 "And there in the darkness of the hotel room, scarcely more than twenty-four hours before the maybe end of the world, the three of them managed to laugh together. It turned out that no amount of terror could stop the great human need to connect. Or maybe, Anita thought, terror was actually at the heart of that need. After all, every life ended in an apocalypse, in one way or another." 
 "You don't wanna go out of this world with regrets. If there's something you want to do, you do it. You take this life by the balls and you tell it that you existed."
