In Moxie’s Problem, Moxie, a teenage princess, leaves her father’s castle for the first time to travel to her betroth’s home. She is escorted by three Knights of the Round Table, Percivale, Gareth and Bors. Along the way Moxie is stunned by the real world, so different from life in the castle. For one thing, the knights ignore her demands and her commands. They expect her to sleep on the ground, get up at dawn and eat what they can catch or find. Moxie notices how independent they are. The knights do what has to be done whether it’s deciding on a route or fighting brigands. Moxie realizes she hasn’t been trained to do anything. She doesn’t have a life.
When Moxie finally meets her betrothed, she hates him on sight, refuses to marry him, breaks the engagement and demands the knights to escort her home. Percivale and the others are reluctant to spend more time with Moxie but finally agree.
Moxie and the three knights suffer through more adventures together as she gradually puts together a plan to make something of her life. Moxie decides she wants to be the queen after her father dies. But her father refuses to name her as successor. Her uncle also wants the crown and tries to eliminate Moxie’s competition.
Meanwhile, Camelot strives to defeat the vicious Saxons on the football field. Merlin, a wizard, investigates the ‘Magic of the Mind’ using primitive Rorschach charts and Stonehenge is a theater-in-the-round. Sir Tristan writes a play that sounds like something Shakespeare will write a thousand years later. The three knights when not escorting Moxie go on quests in Sherwood Forest and what is now Scotland.
