Will he outwit his blackmailer or prioritize his heart’s desire?

NYC billionaire, Daniel Dufort, is being blackmailed into marriage. He’ll do whatever it takes to protect his family dynasty but not that and he’s not about to be coerced into it.

While in Hawaii on business, he meets Harper, and what starts as a sexy distraction soon ends with him questioning his priorities.

Bestselling author Harper Kane is in Oahu where her steamy romance is being made into a movie. Nursing a broken heart, she has no interest in her own love story, especially not with the wealthy, arrogant, and—damn it—gorgeous Daniel Dufort.

Scorching passion erupts between them, but Harper soon discovers his heartbreaking secret and how deceit truly feels.

Sinful Duty is the first book in the Dufort Dynasty series—a steamy contemporary romance, appealing to readers who love fated mates, billionaire romance, and sizzling hot holiday romances with a twist.

With nine books in the series, you can read them in any order and they ALL have a happy ever after.
