But when she bids on a bachelor at a charity auction, the man she wins is millionaire Niall Hunter—who once made intense, passionate love to her and then left without a word. She's determined not to let her guard down again—among other things—around the infamous Irish lothario.

Niall never imagined his penance for one hot-as-hell night with his best friend's little sister would be transforming her from a shy wallflower to a sultry siren. Helping her attract another man is torture...especially when he promised his friend he'd stay away. Plus she wants forever, and he's not a forever kind of guy. But Niall can't stop wanting her.
