Until Midnight by Luanne Rice

When lies and betrayals are exposed, the perfect wedding becomes a nightmare in a gripping novel of psychological suspense by the New York Times bestselling author of Last Night and The Shadow Box.

Rhode Island’s picturesque Ocean House is the perfect setting for Kate Woodward and Conor Reid’s fairy-tale wedding weekend. But there may not be a happily ever after.
When an old friend of Conor’s disrupts the rehearsal dinner and reveals a blindsiding secret—a claim that she and Conor share a child—Kate calls off the wedding, thinking things can’t get any worse. Until the next morning, when that same woman is found with her throat slashed.

As investigators close in and suspicions mount, the evidence points to a mystery deeper than anyone imagined. The soundproof boat with telltale signs of something sinister. The mansion on the hill that lures in young girls and doesn’t let them go. A secret society whose members might be more familiar than not. And the truth of the dead woman’s past that draws Kate and Conor into a nightmare.
