The Color of Water — Lisa T. Cresswell

Life is unpredictable. Why would death be any different? Sixteen year old Samantha's Dad died in a sailing accident and her Mom's moving them to the sleepy, backwater town of Beaufort, North Carolina, so they can make a new start. Afraid to sail again, Samantha takes her mind off the past by trying to solve the mystery of who's killing young women on the island, only the killer is way more than your ordinary psychopath. Turns out, the blood-thirsty ghost of Blackbeard returns to Beaufort on the high tide to collect the souls of beautiful young women and now he wants her mom. With only the help of a two-bit psychic and the ghost of a young, drowned sailor she might be falling in love with, Samantha struggles to save her mother. But Sam has some demons of her own to conquer first.
