The Lying Game Premieres Monday, August 15th, on ABC Family

Tomorrow, Monday August 15th at 9 PM (ET/PT), ABC Family premieres The Lying Game, a mystery series adapted from a young adult novel of the same title by Sara Shepard.

The Lying Game stars Alexandra Chando as Emma, a foster kid who learns she has an identical twin sister, Sutton (also played by Chandro). After their initial meeting, Sutton talks Emma into stepping into her life for a few days while she pursues a lead on the mysterious identity of their birth mother. After Sutton inexplicably fails to return to the girls’ designated meeting place, Emma must decide whether to come clean about her identity and risk her own safety in the hope of uncovering her twin sister's whereabouts, along with the truth about why they were separated in the first place.

The second entry in the planned 4-book series, Never Have I Ever, was published earlier this month by HarperTeen. Shepard is also the author of "Pretty Little Liars" series of young adult novels, which have also been adapted into the ABC Family series Pretty Little Liars, currently airing its second season on the cable network.
