Seventeen-year-old Whit Allgood and his 15-year-old sister, Wisteria (Wisty), think they are normal teenagers until the New Order kidnaps them and accuses them of witchcraft and wizardry. Ruled by an evil dictator known as The One Who Is The One, the New Order has banned all books, movies, music and artwork that promote creativity, imagination or magic. When Whit and Wisty discover they do have magical powers, they use them to escape prison and reach the Freeland. They become part of the Resistance and live with hundreds of other kids in a former department store. Whit and Wisty learn they’re part of a prophecy that calls them liberators. The offspring of Wiccan parents who are also on the run from the New Order, Whit and Wisty are told they will be more powerful than any Wiccans have ever been before them.
As The Gift opens, Whit and Wisty continue to help liberate imprisoned children and bring them into the Freeland. The One Who Is The One stages an execution, telling everyone the victim is Wisty. He actually kills another young Resistance member to draw out Wisty and her cohorts. Whit and Wisty regroup with their friends and begin making plans to infiltrate the New Order’s Acculturation Facility. This “school” is one of the sites where the New Order tortures, indoctrinates and enslaves children.
The Resistance holds a music festival, largely for recruitment purposes. Wisty helps out by playing guitar and is lauded for her abilities. She falls for the drummer in another band. He later betrays her by stealing her magic drumstick and helping the New Order capture her and Whit. While in custody, the kids learn their parents have also been apprehended. The One Who Is The One shows Wisty how he can control the forces of nature, and he urges her to try as well. He becomes angry and frustrated when he sees she has so much power without the ability to harness it properly. The One ships Whit and Wisty to the Brave New World center, a facility where kids are reprogrammed and given highly addictive chocolate as a means of behavior modification. The One’s scientists use several forms of torture on Wisty, trying to make her surrender her gift of magic. When escape seems hopeless, one of The One’s informants, Byron, helps the kids leave the facility in the form of fish through a toilet pipe.
Once Whit and Wisty have returned to human form, they discover and thwart a library burning. Evil adults of the New Order look on in shock as the books they’re destroying begin to fly away under Wisty’s spell. Byron appears with a pack of monster-children the New Order has trained to kill. They chase Whit and Wisty into the Shadowland, where Whit’s dead girlfriend, Celia, exists. Byron reveals Whit is clairvoyant, and he urges Whit to turn himself in so he (Byron) and Wisty can save the children of the Resistance with their combined powers. Whit and Wisty escape, leaving Byron behind to deal with the monster-children. When they exit the Shadowland, Whit and Wisty discover months have passed. Their former hideout in the Freeland has been bombed. They and other Resistance members battle the New Order en route to finding a new place to live.
They visit Wisty’s witch friend, Mrs. Highsmith, hoping she can give them direction. She allows them to talk with their parents in her crystal ball. The parents offer the cryptic message that the kids should give their gifts away. The One arrives, causing natural disasters that show his abilities to control the air, earth and water. He temporarily imprisons Whit and Wisty with their parents, only to vaporize Mom and Dad. Celia and other dead souls from the Shadowland rescue Whit and Wisty just before they’re executed. Wisty, separated from Whit, vows to find him.
