Sunset Shimmer originally went to Freeport to escape Celestia's influence, and to make some progress towards becoming an alicorn princess. She's certainly done her share of good in the infamous city of rogues, but after almost two years away from Canterlot she doesn't feel any closer to achieving her big goals. At this point, any reasonable pony could wonder if they made a mistake...

Faced with the unpleasant prospect of possibly going back to Canterlot in order to advance her goals, Sunset finds herself with one last option to preserve her independence: the great dragon Argentium the Runescaled, far to the north, wants to meet with her. However, her journey becomes far more than a simple social call, and Sunset has no idea just how much danger she and her friends will face.

Or how much she'll have to sacrifice—not just for her dreams, but survival.
