Its spring break and the pretty little liars are trading in Rosewood for a cruise vacation. They want nothing more than to sail into the tropical sunset and leave their troubles behind for one blissful week. But where Emily Aria Spencer and Hanna go A goes too. From scuba diving to tanning on the upper deck A is there soaking up all their new secrets. Emily is smooching a stowaway. Arias treasure-hunting partner is a little too interested in her booty. Spencers going overboard trying to land a new boy. And a blast-or rather a crash-from Hannas past could mean rough waters ahead for everyone. The liars better tighten their life jackets. A perfect storm is brewing and if they arent careful A will bury them at sea. . .
