Our Sister's Grave (Casey White #10)

Panic surges through her lungs as she feels the weight of the ocean above her. She frantically kicks her legs to try and reach the boat. But someone’s grip is tightening around her ankles, and they won’t let go until she’s taken her final breath…

As the sun rises over North Carolina’s Outer Banks, eight sorority sisters gather on the docks, excited to start their reunion weekend with a diving excursion. But when only seven of them return to the boat alive, Detective Casey White is the first person to investigate.

Confused as to why she’s been called to what appears to be a tragic accident, her heart stops when she notices fresh hand-shaped bruises on the victim’s ankles. Karol Witney was murdered. But with a crime scene and any evidence thirty feet underwater, Casey knows this will be her most challenging case yet.

Determined to find the killer, Casey and her fiancé Jericho dive to the shipwreck where Karol was last seen exploring. But just as Casey discovers a piece of shocking evidence on the ocean floor, Jericho is attacked. The killer is still out there, and they’re watching Casey’s every move.

As Jericho fights for his life, and another body washes up on the beach, Casey knows she has to dive again. Because she’ll do anything to catch the killer, even if it means using herself as bait…
