His name is Merc.
He has no past.
Only a thirst for revenge against the traitor who betrayed his team and his country – Agent Jack Mankel.
When he’s handed a mission to rescue a sitting US senator’s daughter from the traitor’s clutches, Merc jumps at his chance for vengeance, never dreaming the girl he rescued could be his downfall…
She walks in the night.
She is a shadow.
An operative so elite even the president doesn’t know of her existence.
Her whole life, she’s lived to serve, raised in the black-ops team her father, Jack Mankel, created. Then her whole world is turned upside down when she learns the sister she once thought dead is really alive; and to save her, Nightshade will have to take on the hardest mission of her life…
Merc knows he doesn’t deserve her. Nightshade knows she can’t have him. But a connection so powerful neither of them can resist draws them closer, even as a betrayal so deep threatens to destroy their very existence.
