3.5 stars here.

I'm not a fan of the "Dear Diary" format as it's introduced in the third installment of this series. Perhaps if the rest of the series had been like that, I wouldn't mind it. As it is, it's just not in the flow with the other two books. Sunny is okay, as far a character goes. He thinks of everything in terms of sounds. He struggles with the fact that his mother died in childbirth with him. His father struggles with that too. But other than that, and Sunny's desire to dance instead of run, nothing much happens in this book. It's mostly just Sunny's self-aware thoughts, that I thought were a bit too self-aware for a pre-teen. It makes me feel like Ghost and Patty didn't have a handle on Sunny at all. They have no idea what's going on in his head.
I do love that Sunny is weird, and creative, and that he owns that. We need more representation of black boys that are vulnerable, or being who they want to be instead of who they're expected to be, and we need representation of black boys who are weird in the best ways.
So, not awful, but still not as good as Ghost. I have hope for Lu. Maybe he can wrap up the series on a high note, because the two middle acts have only been so-so for me.
