After her mother's mysterious death, Kira fled her Texas town and never looked back. Now, decades later, Kira is invited to an old frenemy's vow renewal celebration. Though she is reluctant to go, there are things pulling her home . . . like the urgent texts from her grandmother, who says she has something for Kira. When her grandmother gives Kira a memoir that her mother had been working on before she died, Kira is drawn into the past and all the secrets that come along with it. As she gets closer to discovering what - and who - might have brought about her mother's end, it becomes clear that someone wants the past to stay buried. And they might come after Kira next.
