Lilly and the Pirates

Lilly, a bookworm and notorious worrywart, quells her fears by writing furiously in her worry journal. But when Lilly learns that her scientist parents are lost at sea, she bravely takes the tiller of the Last Chance. In this fast-paced adventure, Lilly must overcome her fear of the sea, find a hidden island, and outsmart a bunch of treasure-hungry pirates.

?This transformation from skittish bookworm to swashbuckling pirate girl is the real buried treasure in this enjoyable preposterous, emotionally resonant, library-revering adventure."
