About This Book

The soft creak of the old rocking chair fills the quiet room, mingling with the faint scent of grandma’s lavender soap. Arlo feels the gentle weight of a secret he must protect, even as the world around him starts to change. What will happen when he sets out to find the family he barely knows?

Quick Assessment

Arlo quietly cares for his grandfather, who is losing his memory to dementia, while hiding how much the boy is doing alone. When a hospital stay brings a social worker and the threat of foster care, Arlo runs away to find the grandmother he barely knows, and the story explores grief, fear, and the hard work of building trust. Its themes of dementia, poverty, and a child running away alone make it a moving choice for readers who can discuss them, with gentle magical realism softening the emotional weight.
