Deadly, the fourteenth volume in Sara Shepard's YA Pretty Little Liars series, delivers more juicy scandals, dark secrets, and shocking plot twists. 

High school seniors Aria, Emily, Hanna, and Spencer have all done horrible things—things that would put them behind bars if anyone ever found out. And their stalker "A" knows everything.

So far A has kept their secrets, using them to torture the girls. But now A's changed the game. Suddenly the girls are hauled in for questioning, and all their worlds begin to unravel. If A's plan succeeds, Rosewood's pretty little liars will be locked away for good. . . .

Toxic is the fifteenth—and second-to-last—volume in Sara Shepard's Pretty Little Liars series.

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.

This penultimate installment of the beloved series is full of juicy scandals, dark secrets, and shocking plot twists that will prepare readers for the jaw-dropping series conclusion in Pretty Little Liars #16.
