This middle grades book explores family, friendship, growing up, justice, secrets, and more. For a middle grades book, I thought that it struck the right balance of serious topics and age appropriateness. The book was well-written, the main character was a delight, and the plot was believable. I do think that the ending (specifically the epilogue) wasn't as strong as the rest of the book. That being said, I will read the sequel once it comes out.
