Dark is the Sea by Heather Blanchard
Haunted by her mother’s disappearance and plagued by nightmares, eighteen year old Rowan Munro abandons London for Dorchay, the remote Scottish village where she spent her childhood. With the help of her eccentric aunt and a familiar face from her past, she unlocks a power in her that is at once terrifying yet curiously addictive. As she uncovers the deeply buried secrets of her family, she awakens something only imaginable in her worst nightmares. The Hunter: centuries old, malevolent, ferocious… and intent on killing Rowan and those closest to her. To survive, Rowan must learn to harness her new-found inheritance, and use her powers to finally confront the brutal, murderous force which has plagued her family for generations.
