Lily, Daisy, and Violet are triplets, but they’d be the first ones to tell you that they’re not identical. Lily likes to read, Daisy is into baseball, and Violet is notorious for losing things—even her homework. When an opportunity for extra credit in science class comes along, Violet accepts the challenge and reports on the similarities and differences among her family members, including the new family dog, Trouble. Author Michelle Poploff and illustrator Victoria Jamieson prove Where Triplets Go, Trouble Follows (Holiday House, $16.95) in this silly, though heartwarming, tale about family, friends, and fun. Ages 7-9. Allison Witten
