Borrowing Blue - Made Marian, #1

Blue: When my ex walks into the resort bar with his new husband on his arm, I want nothing more than to prove to him that I've moved on. Thankfully, the sexy stranger sitting next to me is more than willing to share a few kisses in the name of revenge. It gets even better when those scorching kisses turn into a night of fiery passion. The only problem? Turns out the stranger's brother is marrying my sister later this week.
Tristan: I have one rule: no messing with the guests at my vineyard resort. Of course the one exception I make turns out to be the brother of the woman my brother's about to marry. Now we're stuck together for a week of wedding activities, and there's no avoiding the heat burning between us. So fine, we make a deal: one week. One week to enjoy each other's bodies and get it out of our system. Once the bride and groom say I do and we become family, it'll all be over between us.
Right?
