I would rather write a book than a book description.
I'm re-publishing the Siren Suicides trilogy as one book (down from 260K words to 86K with the help of wonderful @araenel) and this is the best I could come up with so far. Gotta sleep on it and revisit tomorrow.
On a rainy September morning 16-year-old Ailen Bright flees her abusive father by jumping off the Seattle Aurora bridge. In the water instead of death she finds silver-skinned sirens who convert her to one of their own. As a newborn siren she is supernaturally strong, undead, and hungry, and must sing out human souls for food. Her first victim is her best friend and her new enemy is the unnamed siren hunter whose job is to exterminate sirens like vermin. She refuses to kill, at first. With time she must face the agony that comes with starvation, all the while relentlessly prusued. An amazing yet dark look into the mind and heart of a suicidal teenager, this urban fantasy follows Ailen's struggle to figure out the meaning of life, her confusing feelings for her best friend Hunter, and her desperate battle for her father's love.
