Two sisters find they can't outrun their past in the riveting new thriller from the New York Times bestselling author of Northern Spy, a Reese's Book Club pick.

Three years after they narrowly escaped the IRA's worst punishment for informing, Northern Irish sisters Tessa and Marian Daly have built a new life in Dublin with their young children. Though Tessa is haunted by the abrupt and violent end to her old life, she does her best to immerse herself in the joys of Finn's childhood and the rhythms of her new job at the Irish Observer.

It's a small island, though, and just as quickly as they disappeared, figures from the sisters' past surface to drag them back into the conflict. Tessa is told she must track down her old handler from MI5, Eamonn, and attempt to turn him into an IRA informant, or lose everything.

Tessa's reunion with Eamonn revives a host of feelings she has long attempted to bury. As their relationship intensifies and the pressure mounts, long-held secrets rise to the surface, and Tessa must navigate a treacherous landscape of shifting loyalties, all while trying to protect her beloved son.

With her signature hair-raising suspense, razor-sharp prose, and rich emotional depth, Edgar Award winner Berry has crafted both an unforgettable portrait of two fierce women in the Daly sisters, and her most spellbinding thriller to date.
