I Did It For You by Amy Engel

A twisty thriller from the beloved author of The Familiar Dark, in which a woman returns to the town where her sister was murdered and finds a presumed copycat on the loose

It's been fourteen years since Greer Dunning's older sister, Eliza, was murdered, and Greer's family has never been the same. And now there's been a similar killing in Greer's small Kansas hometown, Ludlow, after the execution of the convicted killer. A copycat, according to the authorities, but Greer is convinced there is more to the story. That Eliza's murderer had help all those years ago.

So Greer returns to Ludlow after more than a decade away, desperate to find answers to the questions that have haunted her for years. Her drive to uncover the truth pushes her to form a bond with the unlikeliest of allies.

At once a riveting mystery and a deep exploration of guilt, loss, and the ways in which a violent murder transforms both the family of the victim and the family of the killer, I Did It For You will keep readers captivated through the very last page.
