Harpen Shogan has the rare ability to travel the multiverse without consequences. Harper's boss, Bob Turner, also has a rather long history in the multiverse with those fighting to take down a tyrant ruling it, called the Adventurer's Party. Along the way she meets Naethan, adopted son of guild master Katrina. Naethan's rebellious nature drags Harper across the multiverse, meeting new people from all over the dimensions. They gain new allies and learn new things.
