A note for parents

Sleepless is a mystery-driven novel by a trusted middle-grade author that explores themes of isolation, cooperation, and self-discovery through five teens grappling with an unusual condition. The plot centers on mystery and friendship rather than danger, though the premise of losing sleep might create some unease in younger readers. The emphasis on teamwork and finding answers together provides positive messaging alongside age-appropriate suspense.
