“A mysterious explosion over New York City’s Union Square leaves people’s minds altered, and the only cure may be found in the scattered ashes of a fallen manuscript. Sioux Falls is intentionally split in half—as character’s mind’s are torn left and right, the story allows the reader choose what to read first and when characters collide: a World War II veteran recounts his tragically murky past in Okinawa, Japan; a middle school teacher digs between worlds to try and save it; and a young boy with a contagious illness tries to escape mortal fate in a most unusual way.”
