The accidental newlywed game - Jaci Burton

Wedding planner Honor Bellini is in Las Vegas for a work convention when she runs into her sister's ex-fiance, 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. The longer they keep their secret, the harder it gets to deny how they really feel. They need to get an annulment before this accidental marriage turns into love.
