If I'm being honest with myself, this is probably my favorite book that I've ever read in my life (so far). I love greek mythology with a passion, which may or may not be because of the fact that I grew up with the Percy Jackson series. Either way, this book made me sob like a baby for hours after I read it (and I still tear up even thinking about it, thats how damn heartbreaking it is) and it made me respect mythology even more. It only takes a more modern retelling of the story and character development to turn a ancient greek tragedy into a modern sad story that will make you cry until you can't breathe. 
 I want to marry this book, that's how much I love it. I don't think I will ever read another book that will make me care for the characters as much as I did for Achilles and Patroclus. I just... uGHHHH READ THIS DAMN BOOK AND CRY ABOUT IT WITH ME.

 I reread it and ughhHHHH I love this book so much. I didn't cry as hard as I did the first time, but I weeped into my pillow miserably. I (almost) forgot how much this book made me love classics, how fucking INCREDIBLE it is. Just ahhHHHHHHH I LOVE THIS BOOK OK. Nothing will ever make me cry as hard as I do for Achilles and Patroclus.
