For Better or Worse by Shaw Hart

It was just one trip. How did we end up like this?

Eden Camrie has been Alexander Bronson’s assistant for close to two years now. She’s lasted far longer than anyone else and he tells himself that’s the reason he hasn’t made a move on her.
Instead, he’s been holding himself back from acting on his feelings, burying them behind a grumpy attitude and working late into the night.
Too bad for him that neither of those things scare her off. When they head to Las Vegas to close a big deal, it’s just meant to be a simple business trip. Then the hotel loses their reservation and they’re stuck sharing the honeymoon suite.
No problem. He can sleep on the couch for a night or two. They close the deal and decide to go out for dinner to celebrate.
Dinner leads to drinks, which leads to a Vegas show, which leads to more drinks, which apparently leads to a Las Vegas wedding chapel. Neither one of them remembers getting married, so they decide to stumble around Vegas trying to piece together their evening.
Will these two realize that they’re meant to be together forever? What happens in Vegas doesn’t always stay there.
