Every Heart a Doorway is a fresh take on the modern fairytale that brims with potential. I enjoyed how the book focused on characters from darker worlds, who endured significant horror, but still felt at home there. The writing felt more like a young adult book to me though, the characters felt largely one dimensional and their personalities were spelled out for us by the author. The way the story was narrated was a little jarring to me too, as the narrator often inserted their perspective into the story. Regardless, this was an engaging mystery with creative worldbuilding, and I immediately picked up the next book in the series once I had finished this one.
