Jessie Mason is a normal junior in high school with a boyfriend, a lead part in the school musical, and straight A’s.

But on her seventeenth birthday, her parents reveal her true lineage--that she descends from the first-ever immortal human race--the Community that drank from the Fountain of Youth millennia ago and unleashed mortality into the world. As the daughter of two original immortals who drank, her genes determine her path and Jessie learns she, too, will live forever. But there is a cost.

The Fountain of Youth must replenish its life-giving stores and to do so, it turns those who benefit from the waters into killers, demanding lives as payment for the eternal life it grants.

Paired with Tyler, another (cute) immortal descendant of the cursed waters, Jessie learns to hear and tame the water’s bloodthirsty voice, channeling her murderous impulses toward the Community’s more. . . productive use of her killer instincts.

As she leans into her new identity and grapples for control, she can’t help but feel drawn to Tyler, who may be the only person capable of understanding the sacrifices demanded of her. But someone else knows about her and is threatening to reveal her secrets, or worse. . . 

Can Jessie keep those she loves safe by embracing the directives of the beast within? Or will the water’s call get the better of her, destroying not only who she is, but hurting everyone she cares about?
