New Orleans. 2 a.m. A body comes through a third-floor wall and lands at Mercy Delgado's feet.

She should have walked away. Instead, she knelt in the alley — and survived what came next. Now she carries something in her blood that has no name, a bond to a man who has spent three centuries trying to remain human, and the attention of a world old enough to have buried empires.

Gabriel Marchand has hunted the dark things that move through this city for longer than the city has existed. He has never needed anyone. He has never allowed anyone close enough to need.

Mercy changes both of those things. Whether either of them survives what comes next is only the first question.

ALASTOR'S MERCY is the first book in the Children of Nyx series — dark urban fantasy set in the streets of New Orleans, where the oldest predators alive are the ones still fighting to remain something worth saving.
