Son of Umber and Nyx (Hardcover) (ISBN-13: 9798993451367)

Jessa Whitley survived the Underworld.

Turns out, that was the easy part.

After a summer of brutal training, Jessa is white-knuckling her way through a "normal" senior year, balancing color guard, garage band rehearsals, and pretending the god-brand on her wrist isn't burning hotter by the day. Being drafted as the new Hercules was never part of the plan. Falling for Paul, the immortal guardian she's forbidden to love? Even worse.

When a fatal accident puts her in the path of the god of Death, Jessa discovers Thanatos didn't stay dead. But he isn't the monster she remembers. He asks questions no one should ask, watches her like she's a language he's trying to learn, and keeps slipping into her world like he belongs there.

As the Veil between realms unravels, Jessa's visions bleed into waking life, twisting memory, prophecy, and nightmare into traps built to break her. Something older than the gods is learning her pressure points, using the people she loves as leverage, and turning her own mind against her.

Caught between the god she still loves, the god she can't escape, and a darkness that wants her alive for reasons no one understands, Jessa must uncover what's waking inside her before the Veil tears open for good-and before she becomes something even the gods have no name for.
