Siren

Seventeen-year-old Vanessa Sands is afraid of everything - the dark, heights, the ocean - but her fearless older sister, Justine, has always been there to coach her through every challenge. That is, until Justine goes cliff diving one night near the family's vacation house in Winter Harbor, Maine, and her lifeless body washes up on shore the next day.

Nothing has been normal since Vanessa Sands learned that her sister was murdered by siren femme fatales of the watery depths and that everything she believed about her family was a lie. Her boyfriend, Simon, has been the only person Vanessa feels she can really trust. But now there are some secrets she can't tell even him. And when Vanessa finds herself in the sights of Parker, Hawthorne Prep's resident charmer, she needs someone to confide in more than ever.

A year after the events that killed her sister and turned her into a siren, Vanessa is desperately trying to put her family back together and reclaim a “normal” life. But no matter how many times she swims, or how much salt water she drinks, she can feel herself getting weaker and weaker. She has no idea how to survive as a siren and she doesn’t want to know the truth about her newly discovered identity. It’s just too horrifying.
