Ruthless Temptation by Juliette N. Banks

Aidan Dufort is a billionaire businessman, and dominant lover. During a weekend wedding in Hawaii, he sets his sights on small-town submissive, Lily. The way she reacts to him has his body on fire, and when he finds out there’s another man in the mix, Aidan finds himself staking a claim his family isn’t happy with.
Lily feels completely out of her depth stepping into the luxurious Dufort world for her best friend’s wedding. Add in a powerfully handsome best man who makes her tremble with every glance and this weekend is shaping up to be the wildest of her life.
When promises are made, and responsibilities draw her home, Lily is forced to face reality. She doesn’t belong in Aidan’s world, and this is one demand he can’t make of her.

Ruthless Temptation is book six in the steamy Dufort Dynasty series. It’s part billionaire, part dark romance and will appeal to readers who like spicy books with a strong storyline and characters, witty dialogue, heart-clenching moments, and a delicious happy ever after.
