Grade 4-7-Abandoned at birth, Hollis Woods has lived in about a half dozen homes and has always wished for a family. A foster caretaker describes her as "a mountain of trouble." When Josie Cahill, a retired art teacher, takes the 12-year-old into her home on Long Island, NY, the two bond almost immediately. Hollis draws pictures with colored pencils and Josie carves branches into people. However, it soon becomes clear that Josie has trouble remembering things, and Hollis becomes the caregiver. When she stops attending school, a social worker comes by to investigate. Flashbacks slowly illuminate Hollis's life with one family who had hoped to adopt her and why this didn't happen. Giff masterfully weaves these two strands together in a surprising and satisfying ending. Strong characterization and a solid sense of place are the strengths of this heartfelt story that will appeal to fans of Sharon Creech's Ruby Holler (2002), Katherine Paterson's The Great Gilly Hopkins (1978, both HarperCollins), and Zilpha Keatley Snyder's Gib Rides Home (Delacorte, 1998).
