“You’ll want to live. Because I’m going to make you.”

The city of Saint Leroi—a haven where the twisted order of the underworld converges.

And within it, a spy lurks.

Tessa Ambrose, a C-rank Sentinel under government employment and an undercover operative stationed in Saint Leroi. For over twenty years, Tessa had been unable to find a Guide compatible with her. But there was a reason why the government agency had failed to locate her match.

“So beg me for a kiss.”
