Gr 4–8—Chaya and Maya are identical twins with a strong bond. Maya has been keeping a secret since they were six years old, something even her twin doesn't know about. Chaya picks up on Maya's anxiety and wants to tell their parents, but Maya asks her to keep it undercover. When Chaya discovers Maya is harming herself by digging into to her hand with her own fingernails, seeing the blood shocks her into action. Blaming herself for the anxiety her twin is experiencing, Chaya changes her interests and activities to those different from Maya, to give her space to shine. Unfortunately, Maya sees this as her sister pulling away from her and feels isolated. Each sister feels like the other twin has it easier, so they swap places while at camp—à la The Parent Trap—style musical Long Lost, which they both adore. This novel-in-verse is told in alternating, dual perspectives of Chaya and Maya, which give readers insight into their thoughts and Maya's superstitious secret. LaRocca has created each sister with her own clear voice that is easy to discern as the point of view shifts. The cadence of the lyrical free verse lends itself beautifully to the musical talents of both girls. Family dynamics give readers more understanding and compassion for Maya's perfectionist ways when another family member seems to experience similar pressure that sometimes results in tense situations. Anxiety is presented respectfully, with the goal of helping to remove stigma. VERDICT This engaging verse novel opens doors to more conversations about mental health and deserves a place on every middle grade shelf.—Lisa Krok
