MUMBAI: The writer/creator of the blockbuster teenage drama, Pretty Little Liars, I. Marlene King will soon write the screenplay for the motion picture adaptation of an upcoming teen horror novel. Lionsgate, has acquired the film rights to Daniella Vega’s upcoming book, The Merciless with Alloy Entertainment, a television production unit of Warner Bros. Television. Through her chilling debut, Vega aims to deliver blood-curdling suspense and terror on every page. According to the official synopsis of the book, by the shockingly twisted end, readers will be faced with the most haunting question of all: Is there evil in all of us?

Here is the official synopsis of the book:

Brooklyn Stevens sits in a pool of her own blood, tied up and gagged. No one outside of these dank basement walls knows she’s here. No one can hear her scream.

Sofia Flores knows she shouldn’t have gotten involved. When she befriended Riley, Grace, and Alexis on her first day at school, she admired them, with their perfect hair and their good-girl ways. They said they wanted to save Brooklyn. They wanted to help her. Sofia didn’t realize they believed Brooklyn was possessed.

Now, Riley and the girls are performing an exorcism on Brooklyn—but their idea of an exorcism is closer to torture than salvation. All Sofia wants is to get out of this house. But there is no way out. Sofia can’t go against the other girls . . . unless she wants to be next. . . .

Kirkus Reviews opines on the book that, "It’ll take a sturdy reader not to keep flinching—or put this exercise in sensation down altogether."

Lionsgate recently achieved tremendous success with Divergent, the dystopian teen romance starring Ansel Elgort and Shailene Woodley. The film just grossed a worldwide box office of $260 million including India.

Pretty Little Liars will soon return to Zee Cafe with the fifth season which will deal with the girls, and how they have to adjust to the new world where Alison is in.
