From publisher blurb:
The Grand Stair stretches behind the scenes of the multiverse,
The Doors upon its unfathomably vast span leading the way to gossamer worlds of limitless variety and infinite possibility. Within those worlds reside all manner of people; but there is only one world where the residents are actually fictional!
Planet Fiction, where Sherlock Holmes matches wits with Captain Nemo, where Scheherazade, Cassandra, and Judge Dee Jen-Djieh conspire and scheme. Where, somehow, the characters of Earth's literary past have become flesh-and-blood--and where real flesh-and-blood visitors are in mortal peril! It's fascinating and deadly mysteries notwithstanding, the story of Planet Fiction isn't about the place, it's about the people one meets there.
