Chicago keeps its secrets on the night shift.

Sam Whitfield has worked the ER at St. Anthony's long enough to know exactly what a body can survive, and what it can't. Most nights, nothing saves anyone. That's just the job.

Then a John Doe pulled from the river flatlines on his table. Forty minutes later, with no pulse and no explanation, the man opens his eyes.

He asks for water in an accent that doesn't belong to this century. Then he walks out of a third-floor window before anyone can stop him.

Sam can't let it go. The trail leads him to an antique shop that isn't really open, a woman who's been keeping someone else's secrets for sixty years, and a man named Nico who has been dying, on and off, for four hundred years. Every death takes a piece of him. A name. A decade. Someone he loved, gone so completely he only knows they existed by the shape of the hole they left behind.

Nico is used to losing pieces of himself. He isn't used to someone trying to help him hold onto them.

What starts as one stubborn nurse's curiosity turns into four a.m. diner booths, stolen mornings, and the fragile, particular terror of falling for a man who might not remember your face the next time he opens his eyes. And somewhere in the city, someone from Nico's past hasn't forgotten what he did to survive, and has been waiting a very long time to make him answer for it.

Nine Lives of Sunday is a slow-burn gay vampire romance about memory, devotion, and the kind of love that shows up every time, even when it might not be recognized. Hospital hallways at four in the morning. A diner that never closes. A four-hundred-year-old secret that's about to catch up with all of them.

Some loves are worth relearning, again and again, no matter how many times the world tries to take them.
