I'm not really sure what to think of this book. I liked the 3 different voices, but the characters weren't engaging enough for me. They were all pretty typical, but I can see younger teens and even tweens liking them and relating to them. 
 I liked that 3 kids, who wouldn't have met otherwise, all came together to witness a solar eclipse. Ally was pretty sheltered, since she lives in a campground in the middle of nowhere. Her parents decide that they want Ally and her brother Kenny to experience life in the "real world." It's strange that after a good 10 years in the middle of nowhere, her parents suddenly decide that their kids need to be around kids their own age? But then again, them moving means that Bree has to live in a world that's completely different than the one she's leaving. Bree seemed really spoiled, but she seemed to mature a little throughout the book. Jack was the most interesting of the 3, and it was nice to see that they'd still be friends, even after going back to their lives. 
 I found the astronomy aspect really interesting, and it was done a way that wasn't boring. I even wanted to know a little more, and I'm glad there were some resources at the end of the book. I totally want to see a solar eclipse now. 
 It started off a little slow, but then the pace started to pick up. Overall, it was pretty well-written, and well-paced. And I liked that I knew who was narrating without having to look at the chapter title. 
 It gets a 3 out of 5. It was a little younger than I expected, but still enjoyable.
