Kai is half-Japanese and half-American, living in Japan when the 2011 tsunami hits. After a terrifying few days in which he loses his grandparents and his home, Kai's parents send him to his father's brother in Astoria, Oregon. There lives his female cousin Jet, who is determined to become a river pilot on the Columbia like her father even though it's a difficult job for a woman to break into. She loves sailing, but has lost her favorite sailing buddy, Beck, to his friendship with the obnoxious Roland. Jet's main aim for the summer is to win the Treasure Race, which both her father and her uncle won in their day. She needs a crew. Kai used to love sailing, but now he's terrified of the sea. He's also having a difficult time adjusting to his uncle's family, and missing Japan and his parents (who work at a nuclear reactor). Will he be able to overcome his fear and help his cousin out?
I mostly enjoyed this, though I felt Jet's story and her character rang more true than Kai's. With Kai, I often felt that his emotions/reactions were described but not felt, or just were not present. For example, when he learns that his grandparents have died, he recalls some past memories of them, but there's no sense of any emotion attached to the moment. He just continues with his morning. Overall I got the feeling that the author would from time to time remember, Oh yeah, he had a traumatic time, and then try to reference that somehow, but I didn't always buy it. Jet rang completely true, though, with all her desires and screw-ups and complications with friends getting older. The descriptions of Oregon and the Columbia were mostly good, but I often wished for a map because I couldn't picture things from the description alone (there is a map of the race, but it's at the very back of the book--should have been in front, with a bigger map of Astoria and surrounds, as well as a map of Kai's town, which I also couldn't picture). I thought the book moved along well (though that Swedish festival just came out of nowhere), and I liked the drama of the conclusion. I would recommend this for middle schoolers up to 7th grade.
