Fantasy. Juvenile Fiction. Juvenile Literature. Historical Fiction. Kohei Fujiwara has never seen a big ryu in real life. Those dragons all disappeared from Japan after World War II, and twenty years later, they've become the stuff of legend. Their smaller cousins, who can fit in your palm, are all that remain. And Kohei loves his ryu, Yuharu, but ... ... Kohei has a memory of the big ryu. He knows that's impossible, but still, it's there, in his mind. In it, he can see his grandpa—Ojiisan—gazing up at the big ryu with what looks to Kohei like total and absolute wonder. When Kohei was little, he dreamed he'd go on a grand quest to bring the big ryu back, to get Ojiisan to smile again. But now, Ojiisan is really, really sick. And Kohei is running out of time. Kohei needs to find the big ryu now, before it's too late. With the help of Isolde, his new half-Jewish, half-Japanese neighbor; and Isolde's Yiddish-speaking dragon, Cheshire; he thinks he can do it. Maybe. He doesn't have a choice. In The Lost Ryu, debut author Emi Watanabe Cohen gives us a story of multigenerational pain, magic, and the lengths to which we'll go to protect the people we love.
