It's spring break and Pretty Little Liars is coming to Rosewood for a cruise. They want nothing more than to swim in the tropical sunset and leave their problems behind for one blissful week. But where Emily, Aria, Spencer and Hanna go, so does A. From snorkeling to sunbathing on the top deck, A will be there to soak up all their new secrets. Emily kissed the stowaway. Aria's treasure hunting partner is more interested in getting her own. Spencer's attempt to throw herself overboard will help in the search for a new guy. And an explosion, or more accurately an accident, from Hannah's past could mean tough times ahead. The liars better tighten their life jackets. A storm is coming and if they are not careful, it will bury them at sea...
