Ivy Water

At nineteen, she's still figuring out who she is-a hybrid of mermaid and fae magic that shouldn't exist. College was supposed to be a fresh start, a chance to build a life separate from her overprotective brother Caleb's shadow. But when she falls mysteriously ill, her carefully hidden relationship with Jon, a gentle centaur, becomes the least of her problems. When war erupts and her brother falls, Nilicher must choose: hide the fractured parts of herself, or embrace the integrated magic that makes her uniquely powerful.
She descends into the ancient ocean kingdoms, undergoes a ritual that should kill her, and emerges as something unprecedented-a healer with teeth, an Alpha with a heart, a girl learning that belonging means standing openly in love. The real test is just beginning. As her family fractures under impossible pressure, as the full moon rises and forces the people she loves to their breaking points, Nilicher discovers that the hardest part of growing up isn't managing your power.
