The Garrett — Russell Johnson

The chivalrous time traveler, Paul Garrett, uses cheesy humor and a deep capacity to love others as he continues to fight evil men, wicked politicians, and stand for what he believes is right. He also desires to marry the beautiful overachiever named Cassie Garnier, but to cross that threshold, he must battle demonic forces that try to bring his world to cataclysmic destruction. This is book seven in the Adventure in Time series about teenagers with extraordinary powers of the mind.
