Wedding planner Honor Bellini is in Las Vegas for a work convention when she runs into her sister's ex-fiancé, Owen Stone, who's also in town for his craft brewery business. They're both glad to see a familiar face from home...until a night of drinking leads to waking up in bed together--and a marriage certificate from a wedding that neither of them can recall.

Horrified, Owen suggests an immediate annulment. Honor agrees, but when they spend the day together, their chemistry is overwhelming. Plus, Honor has a flash of memory of their steamy wedding night, and she definitely likes what she remembers. They decide to wait before cancelling the whole marriage thing, though they both head back to Oklahoma determined not to tell anyone at home what happened in Vegas.

The problem is, Honor and Owen can't seem to stay away from each other--or keep their hands off one another. The longer they keep their secret, the harder it gets to deny how they really feel. Even worse, this huge secret has the potential to hurt someone they both care about. They need to get an annulment before this accidental marriage turns into love.
