Filthy Rich (Blackstone Dynasty Book 1) by Raine Miller

Billionaire Caleb Blackstone lives in the glamorous world of wealth and success, with every material luxury. But the moment he sees Brooke Casterley, none of that matters. Caleb is filled with a raw, undeniable need that he can’t ignore…for a girl who is so completely different from everything and everyone he’s ever known.

Only Brooke isn’t looking for love. She knows all too well just how much damage the wrong guy can do. Still, what sane, broke British girl can resist the charms of an incredibly sexy, chivalrous billionaire? What starts as flirtation quickly turns into all-consuming passion. Nothing could have prepared her for the searing heat of Caleb’s touch—or just how much she craves him.

Their whirlwind romance is the stuff of high-society fantasy—but for every moment of pleasure, there is a cost. Past mistakes and tragedy shadow them both…and falling for him might be the kind of trouble she can’t afford.
