Travelers of Time: New Expanded Edition

The Director of the new, top-secret Chronos Project must sort through a group of applicants who want to be time travelers: some are wild and crazy, some are eccentric and quirky, some are brave and brilliant.
One of the best, Emily Baker, meets a famous 19th century author when her ride through time goes awry.
Nicholas McKenna later goes on a mission to stop an evil political leader from ascending to power.
Along the way, Nick encounters other time travelers who are attempting to solve a time paradox. Midway into his mission, Nick experiences a paradigm shift that precedes several surprising plot twists.
In this science fiction novella, Nick learns that both the forces of good and evil can be found on the great river of time.
