Toxic

#1 New York Times bestselling series

The fifteenth book in the #1 New York Times bestselling series that inspired the hit ABC Family TV show Pretty Little Liars.

High school seniors Aria, Emily, Spencer, and Hanna barely survived their most recent encounter with A. And it's not over yet . . . The police don't believe that the real A is still out there, but the girls know what—and who—they saw. If they don't track down this final tormentor soon, A will silence them forever.

Full of unexpected twists and shocking revelations, Toxic is the penultimate book in New York Times bestselling author Sara Shepard’s compelling Pretty Little Liars series. 

• Stalker Thriller: A is everywhere, turning their senior year into a nightmare. With Ali's fanatical "Ali Cats" watching their every move, no one is safe and no one can be trusted.
• Framed for Murder: The Liars have been through a lot, but being framed for a murder they didn't commit is a whole new level of torment. Now they're not just fighting for the truth—they're fighting for their freedom.
• Secrets and Lies: Everyone in Rosewood has something to hide, but the Liars' secrets are deadly. As A closes in, the girls must decide who to trust in a town built on deception.
• Twists and Turns: Just when Aria, Emily, Hanna, and Spencer think they have the upper hand, A reveals another shocking layer of her master plan. In the penultimate book of the series, the stakes have never been higher.
