 "People we love come and go...that doesn't mean we loved them any less at the time." 
 Yes. YES YES YES YES YES. 
 How wonderful it is for a YA author to write a book about relationships and to not make it about romantic or sexual relationships, but almost entirely about friendships? This was done so wonderfully, I'm just incredibly happy it exists. 
 Sara Barnard has written a book about realistic teenage girls who are interested in boys but care far more about each other. They just love each other so much it makes you want to cry all the happy tears. I related so much to Caddy and I just thought all the characters were wonderfully well written. 
 As well as that, this book deals really well with issues such as mental illness and abuse. They're written as oh so very real and important and yet not as though they're the defining factors of the person they affect. It's just so well done, it's so sad and yet so happy and, ultimately, hopeful. So good. All the good.
