Trapped in a parallel universe, office worker Brian has been locked up and charged with starting the snail wars. Steg persuades him to opt for trial by combat against a terrifying warrior called Radnok.

Keen to protect himself, Brian takes a magical crash course from Howell. Steg accidentally becomes a father, Barbara loses her only soothsaying client and the Fairies become obsessed with darts.

It's Munty's famous Pear Fair and Brian and Steg get the easy job of guarding an albino pear tree. Barbara must take advantage of an opportunity to join the Seers' Guild. Howell must fix a card game.

Desperate to reach the City of a Thousand Towers before the Super Solstice, Brian ingratiates himself with a group of travelling Players, in town to stage the annual Munty Play.

It's the Super Solstice, Brian's last chance to get home. He just needs to break into the Protector's mysterious Henge while Howell performs the incantation to cross worlds.
