From the New York Times bestselling author of Pieces of Her comes an electrifying thriller featuring newly minted US Marshall Andrea Oliver as she investigates a cold case with links to her father's past.

A small town hides a big secret.

Who killed Emily Vaughn?

A girl with a secret. Longbill Beach, 1982. Emily Vaughn gets ready for the prom. For an athlete, who is smart, pretty and well-liked, this night that should be the highlight of her high school career. But Emily has a secret. And by the end of the evening, that secret will be silenced forever.

An unsolved murder.

Forty years later, Emily's murder remains a mystery. Her tight-knit group of friends closed ranks; her respected, wealthy family retreated inwards; the small town moved on from her grisly attack. But all that's about to change.

One final chance to uncover a killer.

US Marshal Andrea Oliver arrives in Longbill Beach on her first assignment: to protect a judge receiving death threats. But, in reality, Andrea is there to find justice for Emily. The killer is still out there--and Andrea must discover the truth before she gets silenced, too.
