Stunning by Sara Shepard

The liars are back—and their secrets are more dangerous than ever. Aria, Spencer, Hanna, and Emily thought the truth about A was finally behind them, but someone new is watching. Someone who knows what they’ve done—and isn’t afraid to make them pay.

As lies unravel and the stakes rise, the girls find themselves trapped in a web of betrayal, fear, and obsession. Stunning is a pulse-pounding addition to the Pretty Little Liars series, where every secret comes at a deadly cost.
