Atlas's Grandpa is beginning to forget things. The end of stories, where he put things - and Atlas is worried that soon Grandpa will forget him, too. Mum says that will never happen, not really - but Atlas is determined to fix him.

Skye is forgetting things, too. Like how it feels to have her big sister around now she's left for uni, and the smell of her Grandma's perfume. She's never felt more lonely - until she meets Atlas, a new boy at school who needs her help.

Together Atlas and Skye set out to piece together the missing memories of Grandpa's past - and learn how to live with a future that feels uncertain.

Told in alternating verse and prose chapters between Atlas and Skye, this is a beautiful story about love, memory, and the power of learning to let go.
