Pretty little liars

Hanna, Spencer, Emily, and Aria are trying to move on and forget about their old friend Alison DiLaurentis and all the torture she put them through, but someone is trying to keep her spirit alive.

Before she was murdered and became "A" to the rest of the "Pretty Little Liars" girls, she was Alison DiLaurentis, the most popular, most beautiful, most dishonest girl in Rosewood Day. She had dirt on Emily, Hanna, Aria, and Spencer, enough to keep them from usurping her authority over their clique. However, Alison had a secret worse than all of theirs combined, and in trying to cover it up she set herself in the murderer's sights.

Four girls living in a wealthy suburb discover the identity of a stalker who has been sending them shocking text messages, and uncover the mystery of who killed their childhood friend.

A collection of four stories from Sara Shepard's Pretty Little Liars series, chronicling the adventures of Hanna, Emily, Spencer, and Aria during the winter break between "Unbelievable" and "Wicked.".

"It's 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. Aria's treasure-hunting partner is a little too interested in her booty. Spencer's going overboard trying to land a new boy. And a blast-or rather, a crash-from Hanna's past could mean rough waters ahead for everyone. The liars better tighten their life jackets. A perfect storm is brewing, and if they aren't careful, A will bury them at sea..."--Dust jacket.

Aria is having boy trouble, Emily is exploring her wild side, Hanna finds romance with an enemy, Spencer is haunted by someone from her past, and A learns a secret that the four high school seniors thought would not leave spring break.
