Last Night I Sang to the Monster by Benjamin Alire Sáenz
Again, I have no words to describe how much I liked it. Benjamín Alire Sáenz is now one of my favorite authors.
He treats subjects like addiction, depression, ptsd with a delicacy and knowledge that makes the reading very compelling.
The book just flies, when you realize you're like 10 pages away from the end. It's impossible not to care for the characters and even identify a little with some of them in one way or another.
It's a lovely, deep story with real and daily subjects.
