I've had this on my to read list for years, and I'm glad I finally got around to reading it. While I feel for Caleb, this was a very solid read from the POV of Black people in the era of Jim Crow, with a Lovecraftian spin. A far more enjoyable read than some other period pieces.
It's been a few years since I last read the series, but I don't remember liking this one as much as the first. But after reading it again, I really like it. Mostly due to the subversion of the heroes journey we got in the first book. That warning about charismatic leaders shines brightly here.
I'm surprised how much I enjoyed this, despite Ax being my least favorite character. I didn't love the blatant sexism from him and the male Andalites, but there were some fun moments in this book.
