First of all, best character name ever. Sounds just like someone with whom I would have gone to high school! Middle grade literature has been having characters with a wider variety of challenges when it comes to medical conditions, and this is the first instance of someone with pernicious motion sickness. This is also the only book I can think of where the main character has an interest in traffic patterns. The details about life and driving in Los Angeles that go along with this are enlightening and make the opening scene in La La Land make so much more sense! All of the little elements (Polish food, economic difficulties, fiesty abuela with a HAM radio, hanging out with Girl Scouts) added up to a fun story. I also appreciate how invested in biking the author is!
Public art is interesting; I'm a big fan of yarn bombers, even though I would rather knit a sweater. The idea of taking old highway signs, decorating them, and putting them up along the highway, will appeal to young readers. It sounds dangerous and expensive to me. What if the duct tape and paint come off and the sign tells people to do something that's just wrong? I worried way too much about this, but students won't.
