When a failed experiment accidentally drops Darcy Lewis into the middle of Asgard, she finds herself an unwilling guest of the God of Mischief. However, as the two of them are forced to spend time together in each other's company, she begins to wonder if being his prisoner may not be so bad after all. (Of course that might just be her ladyparts talking)
Set prior to the first Thor movie, and will diverge from canon because I'm a total rebel like that.
