Jack Wells is back in the saddle again – literally! Along with fellow time travelers Simon & Elizabeth Cross, Jack travels back to the Old West for another rip-snorting, time-bending adventure!

It's 1879 and President Rutherford B. Hayes (Remember him? No? Anyway...) is touring the West by train. It's a shrewd political move and a campaign promise fulfilled. There's just one problem – someone in Dodge City has other ideas and plans to assassinate the president, killing everyone on board.

Now Jack, Simon, and Elizabeth must discover who is behind the assassination plot and stop it before it begins. But first, they have to survive the wild, reckless, and violent streets of "The Wickedest Little City in the West." 

Nothing short of the fate of a nation – and the future – lies in the balance!
