Squirrels Sage and Sorrel are just the same: they like the same games, sing the same songs and say the same things at the same time. They even have the same stripe on their tails! But when Sage invites her friend for a sleepover, Sorrel discovers they aren’t the same at all! So, while Sage has a huge family and an even bigger treehouse home, Sorrel lives with her mum in a tiny tree. Sorrel must hide how different she is, otherwise Sage won’t be her friend – or will she?
