The drowning kind : a novel
(Book)

When social worker Jax receives nine missed calls from her older sister, Lexie, she assumes that it's just another one of her sister's episodes. Manic and increasingly out of touch with reality, Lexie has pushed Jax away for over a year. But the next day, Lexie is dead: drowned in the pool at their grandmother's estate. When Jax arrives at the house to go through her sister's things, she learns that Lexie was researching the history of their family and the property. And as she dives deeper into the research herself, she discovers that the land holds a far darker past than she could have ever imagined.
