Blackwater's most powerful criminals fear the man they call The Devil.
For six years, victims' rights attorney Maeve Arden has searched for the sister who vanished without a trace. Then a black envelope arrives. Inside is a stolen ledger page in Mara's handwriting and an invitation from Lucian Voss, the cold, brilliant strategist behind the Black Covenant, a secret vigilante network that punishes the criminals the justice system cannot touch.
Lucian promises Maeve the truth, but only if she helps him infiltrate the Blackwater Renewal Trust and expose Victor Harrow, the celebrated philanthropist hiding blackmail, witness tampering and murder behind his respectable name.
Maeve is certain Lucian knows more about Mara's disappearance than he admits. Lucian believes Maeve's late father helped bury the crime that created the Covenant. Forced into a reluctant alliance, they follow a trail of silenced witnesses, coded records and family secrets while fighting an attraction neither of them can afford.
But Lucian has built his power on control, and Maeve refuses to become another choice he makes for someone else's good. As the truth closes in, Lucian must decide what he is willing to destroy to keep her alive, and Maeve must decide whether trusting The Devil will lead her to her sister or cost her everything.
In Blackwater, justice has a price. Love may demand more.
