A twisty thriller from the beloved author of The Familiar Dark, where a woman returns to the town where her sister was murdered and finds a copycat on the loose. It's been fourteen years since Greer Dunning's older sister, Eliza, was murdered, and Greer's family has never be the same. But after the execution of the killer convicted, there's now been a similar killing back in Greer's small Kansas hometown, Ludlow. A copycat, according to the authorities, but Greer is convinced there is more to the story. That Eliza's killer 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 pushing her to form a bond with the unlikeliest of allies. And, just maybe, save herself and her family. At once a riveting mystery and a deep exploration of guilt, loss, and the ways in which a violent murder transforms a family and a place, I Did It For You will keep readers captivated through the very last page.
