A portal tears apart the barriers between worlds, dragging Emma and Hook down with it. The search for the portal that will lead back to Storybrooke detours through new lands and old territories where things are no longer the way they were. Trust is no longer an option, any alliance is temporary and each fight is worse than the last. Captain Swan.

AU! Princess Emma and Lieutenant Killian are both to be engaged, but there's a slight problem. They both hate each other. Two weeks on a ship with one another may be just the thing they need to get something to spark between them.

A captain swan AU that turned into something else...

Emma likes to sleep with her window open. She never quite realized who she'd be inviting in. All things considered, however, Captain Hook showing up in her bedroom after midnight is hardly the worst of his offenses. Emma knows how to handle Hook. (AU post "Welcome to Storybrooke". Unapologetically Captain Swan.)
