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

New York billionaire, Daniel Dufort, is being blackmailed into marriage by a US senator. He'll do whatever it takes to protect his family dynasty, including recruiting a private security company full of former black ops. Marriage was never on the cards for him and he's not about to be coerced into it. Then Daniel meets Harper, and what starts as a sexy distraction soon ends with him questioning all his priorities.

Steamy romance author Harper Kane is in Hawaii for business. She has zero interest in a holiday romance, especially not with wealthy, arrogant, and—damn it—gorgeous Daniel Dufort. 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.

"This is 100% my favorite book from you so far. You can write some damn good contemporary romance! So a 5-star for sure! If 6 stars were a thing I'd do that!" - Taylor D

"It's very steamy! I loved how Daniel brought Harper out of her shell. Super hot! Just glad my eldest wasn't reading over my shoulder. LOL." - H Brown Maddox

    Juliette had me hooked from the beginning to the end of this book. The Dufort men are dynamic, sexy & alluring, and Daniel pushes all the right buttons with his brooding demeanor 🥰 I love a serious Alpha Male! I gave it 5 stars because this book everything I love in a Romance, the right amount of angst, steam, a lil suspense & drama and a happily ever after. And of course the intimate scenes are 🔥🔥🔥😉 Definitely gonna read the other books in this series! Here we go!🥰

    One thing ruined the book for me- a category 5 hurricane hit the island and there was just a little “debris of palm fronds and signage”. No broken windows, no roofs sucked off the buildings, no power outages. They even went shopping the next morning because miraculously, nothing was damaged from 150 mph winds of a cat 5. Hello???

    I love a good erotic but interesting book! I really recommend if you love reading cheesy romance books! The story is good, the semi twist is good. I like that Olivia didn’t choose Cooper. I’m definitely buy the second book!
  • Must read!
