This was wonderful and cozy. I'll note upfront that Ellie is 17, but the book still felt a little more like a middle grade novel to me. Still, it was so much fun. Being indigenous myself, I wish I had this as a younger kid.
It's set in our world, but with things like ghosts, monsters, and magic (I particularly loved the first short encounter with the vampires and how they dealt with them!). There's some Lipan Apache mythology, a murder mystery, and some supernatural animal sidekicks. It's not scary, but there is a horror to the secrets that give you something to think about. The pacing was great, and I was just along for the ride. And I loved the casual ace representation - there was no forced romance subplot or whatever to add unnecessary drama. The illustrations were excellent too.
