When Ira's Job lets him go because of his injury he figures his safe, predictable life is over. Forced to take a lesser paying job at a hotel is boring, but when Ira learns that friend in his author group has come from the future to protect him, and that his co-worker is an assassin sent to kill him, suddenly Ira's not-so-exciting life takes a different twist. Now Ira has to stay alive long enough to write a book that will change the shape of the world one hundred years from now.
