This is between 3.5-3.75 stars for me. I love the idea of this book. Doorways that lead to magical worlds? Sounds enchanting. While I loved the characters and how quick this is, I'm not sure how I feel about the lack of details for these worlds. It's almost like you're given just enough detail to have a basic understanding or as if you're on the outside looking in and not immersed in these worlds. It's not something I'm used to in fantasy.
