Desire Unbound by Juliette N. Banks

When Jackson, a Forbes 500 tech genius, discovers his real father is the founder of the Dufort billion-dollar dynasty, he inserts himself into their world by dating Kristen. A sassy siren, with eyes like emeralds, who’s visiting them in New York.
Furious, when she discovers his true identity, Jackson convinces her the hot sparks between them are real – hello, that f*cking kiss!, and to spend her last four days in his arms. Or rather, his bed where he intends to show her real dominant pleasure she’ll never forget.
Falling for her wasn’t the plan, yet his priorities begin to shift until she does the one thing that could destroy them.
Will the secrets Jackson holds jeopardize everything? Or has Kristen’s actions caused the collapse of their bond already?

Desire Unbound is the fourth book in the Dufort Dynasty series—a steamy contemporary romance, appealing to readers who love billionaire romance, fated mates, age-gap and the more erotic romances with great storylines and happy ever after’s.
