A Life Full of Lies

by Heather O'Brien

What if the truth shatters everything you thought you knew?

Aaron Callahan never knew his half-sister Lydia until her Book of Life revealed the secrets she left behind. What begins as a search for answers quickly unravels into something family lies buried for decades, betrayals no one dared confront, and memories so fractured they threaten Aaron’s own grip on reality.

With his wedding approaching, the past he’s tried to outrun closes in. Each discovery pulls him deeper into Lydia’s haunted world, forcing him to question not only his family but his sanity. The closer he gets to the truth, the more dangerous the journey becomes, and the more he risks losing everything he loves.

A Life Full of Lies is a literary thriller about family betrayal, hidden trauma, and the devastating cost of uncovering long-buried truths. For readers who loved Sharp Objects, We Were the Mulvaneys, and The Poisonwood Bible.

Previously published as Book of Lydia.
