When the Squirrels Stole My Sister — Catherine Austen

My sister tamed a squirrel with peanuts until it ate out of her hand... So begins a tongue-in-cheek tale of taming gone wrong. When a genius squirrel launches a daring winter storage plan, big sister ends up high in the oak tree with a new furry family. But what will happen when they run out of nuts? It's little sister to the rescue!
