Catherine Thorne knows exactly what kind of men thrive in Corinborough.

As the madam of one of the city's most exclusive houses, she has spent years watching powerful men indulge their worst appetites behind closed doors—and watching wealth, position, and influence protect them from the consequences. But Catherine has never been particularly interested in waiting for justice.

By night, she becomes the Raven.

Detective Christian Sinclair has devoted his life to the opposite belief: that justice must answer to the law, even when the law is imperfect. When a string of carefully chosen men begin turning up dead, finding the Raven becomes more than another investigation. Someone is deciding who deserves to live and who deserves to die, and Christian cannot allow that judgment to belong to a single person.

Then he meets Catherine.

What begins as attraction becomes something neither of them intended. Christian finds himself drawn to a woman who challenges everything he believes about power, morality, and the city he has sworn to protect. Catherine, meanwhile, discovers that the detective hunting her is far more difficult to dismiss than the badge he wears.

But Corinborough is built on secrets, and Catherine's is only one of them.

As Christian's investigation draws him closer to the Raven—and closer to Catherine—they will both be forced to decide what justice is worth, who gets to define it, and what happens when the person standing on the other side of that line is the one you cannot bear to lose.
