King Snodd IV of the Kingdom of Hereford has realized that the power of magic has untold financial possibilities, and the man who controls magic controls almost anything. To this end, he has appointed as Official Court Sorcerer the odious Blix at Industrial Magic, one of only two Houses of Enchantment left in the world. With Blix's willing assistance, only one person stands between King Snodd and his plans for power and riches.

Jennifer Strange, the sixteen-year-old acting manager of Kazam, runs the only other House of Enchantment. She doesn't care for King Snodd or his plans for magic. Ancient decree dictates that Kazam can refuse Snodd's demands, but Blix challenges Kazam to a contest: the first team to rebuild their half of Hereford's collapsed 12th-century bridge gains control of the other's House of Enchantment.

With only one functioning Wizard and her faithful assistant, Tiger Prawns, Jennifer must use every ounce of ingenuity to derail King Snodd's plans. It may involve a trip on a magic carpet at the speed of sound to the Troll Wall, the mysterious Transient Moose and a powerless sorceress named Once Magnificent Boo. Only one thing is certain: Jennifer Strange will not relinquish the noble powers of magic without a fight.
