Mabel Hsu at HarperCollins/Tegen has bought Corey Ann Haydu's Tree, a middle grade novel inspired by the Greco-Roman myth about Daphne and Apollo. The book follows Daphne, a girl who feels most herself in the outdoors, usually next to a river where she has always felt safest. But when a new friendship with classmate Apple turns toxic, the river does what it always has, protects Daphne—by turning her into a tree.
