Her Wicked Captain by Sandra Jones

She played right into his hands.

The River Rogues, Book 1

Possessing uncanny people-reading skills like her mama, Philadelphia “Dell” Samuels has spent thirteen years in her aunt’s rustic Ozarks home, telling fortunes over playing cards and trying to pass as white. But the treacherous Mississippi River childhood her mama dragged her away from finally catches up to her on a steamboat captained by her old friend Rory Campbell.

Known to his crew as the Devil’s Henchman, Rory is a gambler in need of a miracle. Following the cold trail of his boss’s wife and bastard daughter, Dell, Rory has only one goal in mind: saving his crew from the boss’s cruelty by ruining him. The only one who can defeat the Monster of the Mississippi is the man trained to take his place. Rory’s convinced he can lure his boss into a high-stakes game against a rival, and with Dell’s people-reading skills, the monster will lose everything.

Under Rory’s tutelage and protection, Dell agrees to the tortured captain’s plan. Passion and peril quickly bring them together as lovers. But when Rory’s plan goes awry, the lives of the innocent depend on Dell’s ability to read the situation correctly—and hopefully save them all.
