Now a TV show airing on Freeform, starring Pretty Little Liars favorites Sasha Pieterse and Janel Parrish!

Ava, Caitlin, Mackenzie, Julie, and Parker are all driven to be perfect?no matter the cost.

At first the girls think they have nothing in common, until they discover that they all hate the same person: handsome womanizer Nolan Hotchkiss, who's done things to hurt each of them.

They come up with the perfect plan to murder Nolan?jokingly, of course. They'd never actually go through with it. But when Nolan turns up dead in the exact way they'd discussed, the girls suddenly become prime suspects in his murder.

Only, they didn't do it.

So who did? Unless they find the real killer, and soon, any one of them may be the next to die....

Fans of the Pretty Little Liars series and TV show will find The Perfectionists packed with the same kind of juicy secrets, taut suspense, and jaw-dropping surprises that they've come to expect from New York Times bestselling author Sara Shepard.
