Midnight Waters by Rosie Wylor-Owen

“In my family, when someone is born, another will die.” A symbiotic curse has plagued the Arrowood and Everhart households for generations. When a new baby is born, a member of the ancient clans die. Only a truce between the warring families can break the deadly hex once and for all. Upon hearing her cousin is in labour, Maeve Arrowood hurries home to find out which one of them will be next. But the loss of her uncle is the least of her worries when a young man is found dead in the sea under suspicious circumstances. Called in by the police, Maeve has no option but to reprise her role as a scuba diving police consultant to retrieve the body. Unwittingly drawn into the investigation, Maeve is forced to work with the odiously handsome Ben Everhart. Obliged to put aside their differences, Maeve and Ben soon discover that a far deadlier danger has descended on the island of Dusk. One that could destroy both families forever.
