Look What You Did is a page-turning debut thriller for fans of Kathleen Glasgow and Megan Lally. It's a gripping tale about a teen who must confront her own buried trauma to clear her friend's name of murder and expose the dark secrets of her small town.

"I know what Will did that night. He deserved what happened to him."

After the tragic death of Cold Creek's golden boy, Will Ashford, the entire town is in mourning. That is... almost everyone. When seventeen-year-old Mackenzie gets the news, she couldn't be more relieved. She knows Will's veneer of perfection hid something dark and dangerousβ€”a truth she learned one night at the Ashford house that she swore never to tell.

But her plan is threatened when she starts receiving texts from an unknown number. Someone knows the secret Mackenzie has tried so hard to hide and is determined to reveal it.

When her former best friend is found dead, Mackenzie is convinced that her anonymous texter is behind the murder and will stop at nothing to find them. But doing so will mean confronting the trauma she's fought to suppress and exposing dark secrets her seemingly perfect suburban town will do anything to keep buried...
