When Lily and her family move in with her sick grandmother, a magical tiger straight out of her halmoni’s Korean folktales arrives, prompting Lily to unravel a secret family history. Long, long ago, Halmoni stole something from the tigers. Now they want it back. And when one of the tigers approaches Lily with a deal–return what her grandmother stole in exchange for Halmoni’s health–Lily is tempted to agree. But deals with tigers are never what they seem! With the help of her sister and her new friend Ricky, Lily must find her voice…and the courage to face a tiger.
