Steeped in mystery and adventure, this brisk and beautifully crafted middle-grade debut set in modern-day India explores the complexities of the sibling bond.

When her older brother, Karthik—Kay-Kay, the golden child of the family—heads to camp for two weeks, Lena’s parents begin showering her with all the attention she craves. For a time, she’s the golden child and secretly wishes her brother wouldn’t come home. But when the scheduled train arrives and Karthik isn’t on it, Lena is stricken with guilt and fear for her beloved Kay-Kay. Her brother has vanished without a trace, and the police view him as a runaway. Incredulous, Lena undertakes a search of her own—reading mysterious poems left in his backpack, interrogating his fellows from the train, retracing his route, and encountering shadowy strangers along the way. Convinced Kay-Kay is still alive even when the rest of her family has given up, Lena steadily unearths her brother’s secrets as her determination to bring him home leads to a heart-stopping discovery. Perhaps Kay-Kay isn’t a golden child after all? Set in a vividly evoked modern-day India, this character-driven middle-grade mystery tackles rich themes—from the sibling bond to self-worth—in a taut and suspenseful adventure.
