I've heard so much about Siobhan Dowd's writing. I've even read one of her books. But I was never quite sure what it was that everyone lauded so much. Now, having read A Monster Calls, which was inspired by an idea from her (although how MUCH she left behind after her death, I couldn't say), I can see it. 
 A Monster Calls is beautiful and sad and crawls into your heart and tears it. And heals it a little, too.
