The Julia Gillian books (which consist of this one and the first book, Julia Gillian and the Art of Knowing) are a bit of an enigma. Why do I love them so much? Nothing much happens; Julia worries alot, so she spends a lot of time ruminating while taking walks with her dog, Bigfoot. I think the real joy (pun intended) of these books is in the way McGhee writes her characters. Yes, Julia may not be searching for 39 Clues or going to Camp Halfblood, but she is more interesting to me than the kids in those books (and I like those books, btw). We may not see Enzo doing much besides sitting in a pretzel position, but she's still one of the best role models going in children's books. And Julia's parents aren't flamboyant like a Lucius Malfoy or Grandpa Joe, but they interact with Julia in a wonderful, realistic way. When you put it all together, you get truly memorable, beautiful books.
This one wasn't quite as good as the first, but still tons better than most. Julia is at school now with her best friend, Bonwit, but things quickly go south when the beloved lunch lady is hurt. Soon "Dumpling Man" (so named because of a shirt he wears) arrives, leaving terror - and baby carrots - in his wake. Plus, Bonwit is keeping a secret, Julia Gillian can't figure how to make a sound on her trumpet, and finally Julia starts layering lie upon lie (and feeling guilty). The reasoning behind all of the secrets makes sense (sometimes in surprising ways) and Julia eventually does, indeed, find joy.
