One forced vow One devastating truth One forbidden obsession London, 1865 Born a baron's daughter, young Evangeline Brimworth knows a thing or two about aristocracy's politics. Though she never thought she'd be the bargaining chip. When her family winds up penniless and her hand in marriage is sold to a man old enough to be her geriatric grandfather to restore their fortune. But Evangeline refuses to be caged without a fight-and she's willing to risk everything to escape. The last person she expected to get in her way is her stepson. Azriel Caine. Cynical, mysterious, and seemingly following her every step. Because somehow, he holds a dangerous secret about her over her head, and unless she wants to destroy her reputation, she must do as he says. Including wed him. Their impropriety is nothing new for Azriel, and he hardly cares. He believes in obsession. In possession. And the more Evangeline peels back his layers, she finds herself craving his darkness almost as much as she fears it. Fans of Bridgerton craving the scandalous, wicked underbelly of high society will devour this dark, taboo romance from bestselling author RD Baker that will leave you swooning, reeling, and gasping at every turn.
