Time Travel Rule #1: Don't interact with anyone for any reason.

Yeah, right.

CIA field agent Ryan Cochrane thought testing an experimental time machine would be just another assignment. Then a police dog damaged the activation switch on his arm and stranded him twenty years in the past.

Getting home should be simple: find the theoretical physicist who helped make time travel possible and get him to repair the switch.

There's just one problem.

That physicist is Ryan's father.

In Ryan's time, both his parents have been dead since he was thirteen. Twenty years in the past, they're alive again, his younger self is just down the road, and every conversation risks changing the future. Ryan knows the rules. Don't interfere. Don't reveal who he is. And above all, don't change anything.

Then the timeline begins changing anyway.

Each attempt to put history back where it belongs creates new consequences, new dangers?and new reasons for Ryan to question whether restoring the past is really the same thing as making things right.

Because when you've been given an impossible second chance with the people you lost, saving the future may mean losing them all over again.

Assassinating Yesterday is the first book in the Project Gateway series, a fast-moving time-travel thriller combining action, government intrigue, altered timelines, dark humor, and deeply personal family stakes.
