Cosmo Rabbit and the Sour Grapes is a warm, whimsical children's chapter book about honesty, kindness, and the courage to ask for help.

When Cosmo discovers that the sweetest grapes in his garden are disappearing night after night, he and his friends set out to catch the mysterious thief. But the culprit isn't who they expect—it's a young fox from a faraway, dusty planet who has never known what fresh grapes taste like.

Inspired by the classic "sour grapes" fable, this gentle space-garden adventure teaches young readers that wanting something isn't wrong, asking takes bravery, and kindness can grow into something much bigger than anyone imagined.
