From the back of the book:
Yikes on Toast!
One moment you're touring your uncle's military base, and the next you're emerging from a strange steel-and-ceramic closet four hundred years in the future. And 24th-Century Earth is a world gone wacky- a place called Gamma World.
As Jason Montgomery, dogcatcher-turned-president, you and H.O.B.A.R.T., your artifically intelligent power armour, become the guardians of freedom for all civilization. Your face ruthless robots, animal mutants, vampire dentists, biker librarians, cyborg pirates, and more. But in order to secure your newborn nation, you must enlist the aid of a ragtag group of noble knights on horseback...
For only you can rally the American Knights!
