I enjoyed this sequel to Brendan Buckley's Universe and Everything in It. It's not about racial identity (but the book's characters are racially diverse). It's more about growing up and navigating friendships. This one also concentrates on Brendan's relationship with his dad (where the last one concentrated more on his relationship with his mom).
Occasionally plot points were left hanging a little too long, and there are a lot of metaphors (I'm not the biggest fan of metaphors), but the sequel left me wanting another sequel.
ETA: The black belt myth is replicated in the book (you know, everyone's belt starts out white and becomes stained until eventually it's black). Also, Frazier uses n**py to describe the weather (this is a personal thing, but I HATE that word).
