Legendborn

This was really interesting and more complex world-building than most YA I've read - mixing Arthurian legends (which I have never found interesting enough to read much) with Black history and magic and showing (not just saying) “it takes strength to survive and thrive” is a pretty interesting combo. The characters and relationships weren't always heavily developed due to the world-building priority, but that's an understandable choice. There were interesting twists that added a lot, and I enjoyed this enough to go right to the sequel.
