Caspia‘s summer is transformed when she discovers a bundle of letters containing ten plant-based riddles in this enchanting adventure.

When Caspia learns that her family are moving to Brooklyn for the whole summer, she can’t believe her bad luck. No sleepovers with Ellie and Larissa? No trips to the mall? Just tall, glassy buildings and “city people”—it’s the worst news ever.

But when she discovers a bundle of dusty letters on her first evening, everything changes. Each letter contains a riddle about a plant—a citizen of a mysterious world called the Green Kingdom. On a quest to discover the secrets hidden in the clues, Caspia walks the concrete streets of New York, making friends in unexpected places and finds that happiness can be found anywhere if we are just brave enough to put down new roots.
