The drowning kind / Jennifer McMahon.

When Jax receives nine missed calls from her sister, Lexie, she assumes that it's just another one of her 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. In 1929, 37-year-old newlywed Ethel Monroe hopes desperately for a baby. In an effort to distract her, her husband whisks her away on a trip to Vermont, where a natural spring is showcased by the newest and most modern hotel in the Northeast. Once there, Ethel learns that the water is rumored to grant wishes, never suspecting that the spring takes in equal measure to what it gives.
