I put off reviewing this one, because I'm not sure how I feel about it. It had compelling characters with interesting stories (including a trans character,which is so rare to find in books like this), very cool imagery and storytelling, and an interesting set-up. I would recommend reading it for all of those reasons. 
 My uncertain feelings come from some of the implications of the story. Every Heart a Doorway is about a school of kids who are left at loose ends after they're dumped out of their magical adventures. Think Alice back in England with no hope of return to Wonderland or the Penvensie kids back home and the wardrobe shut tight behind them. 
 All of them want to go back to their magical worlds because something about each one of those is catered to them in a way that our world isn't. When they comeback, the world doesn't seem to fit and their parents don't understand or don't listen to what their kids are saying. I love that this book validates the experiences of kids in a very real way. 
 My problem was that some of these other worlds that the children belong to do things in a way that would definitely constitute child abuse in any real context. For that reason I'm a little uneasy about the narrative supporting their desire to go back to those places. 
 I'll be reading the next in the series when it's published. I'm interested to see what happens.
