Rebirth
Part of the Time Guardian series
When a brilliant scientist builds a time machine to rewrite his traumatic past, he and his team are thrust into a dangerous mission that spirals out of control. Before he could accomplish this personal mission, the FBI commissioned him and his team to prevent a terrorist act in the past. Unfortunately, these two missions took a back seat to their accidental entrance into different historical events. How can they stop their time-hopping, restore history to its proper state, and return home safely? Not only are they traveling through time, but they are racing against time.
