The Sirens of Pacific Grove, California are being exterminated, and seventeen-year-old Loralei Reines is their next target. Lora may look like a normal teenager, but her voice has the power to enchant and hypnotize men. Like the other Sirens in her clan, however, she keeps her true identity a secret to protect their species. Lora's birthright as the next clan leader seems far off, until the Sons of Orpheus, a vicious cult determined to kill all Sirens on Earth, begin exterminating her people. When an unexpected tragedy occurs, Lora must take her place as Guardian of the Clan. Lora is determined to gain control of her skills to help her clan, but they are developing too slowly, until she meets Ryan, a human boy. When Ryan is near, Lora's abilities strengthen. She knows she shouldn't be with a human. Yet, she can't resist her attraction to him, or the surge in power she feels whenever they're together. And the Sirens are running out of time. If Lora can't unlock the secret to defeat the Sons of Orpheus, she, along with everyone she loves, will be annihilated.
