When Stars Collide

We were like two stars orbiting each other-dancing around the possibility that one day we might collide. When we finally did, we opened up a black hole, obliterating everything around us. No one would be the same.
Least of all, us.
Waking up in Vegas married to the guy of your dreams sounds like a good thing, right? Not when you're Thea Montgomery and said guy is your brother's best friend.
Thea and Xander have always avoided the connection between them because her brother would never approve. Now, they're married- the strongest bond you can have as a couple-and they're not even a real couple...unless they want to be.
Thea wants an annulment immediately, but Xander's waited too long to see her become his and he won't let her go easily.
If she wants a divorce, fine, but he wants the summer to convince her that he's the one. If at the end of the summer she still wants to end their marriage he'll sign the papers, but until then...
All is not fair in love and war.
