Take them away! They shall never see their parents again until the day they all die.
The book begins with an Execution. The Allgood's Execution. Wisteria Rose Allgood, or "Wisty" seems to be telling the exposition / Prolouge.
The events that 17-year old Whit and his 15-year old sister Wisty go through begin one night at their house. The siblings are accused of being a witch and wizard by the New order. Wisty accidentally reveals her powers, then the one who is the one gives them a chance to renounce their former existences, including their parents. They refuse, and are sent to jail.
The Algood sibllings escape from jail with Whit's dead girlfriend, Celia, and a strange, but passive, kid named Sasha. A chase scene occurs between them and some lost ones (Read: Evil, cannibalistic ghosts). Oh. Yeah. Byron Swain turned into a weasel, but I couldn't find one, sooooooo, he's a mouse.
Whit and Wisty, along with a *Seemingly* innocent kid named Jonathan go to the city of progress to meet the enemy from freeland. Wisty throws a fork at herself (With magic.), and after the Ms. Highsmith incident, get back to Garfunkel's. Sasha tells the siblings that their mom and dad have been captured, so they agree to go on a prison raid to rescue a bunch of kids.
During the jailbreak, Wisty finds out Sasha LIED about her parents being captured again, and that Jonathan is a dirty, backstabbing TRAITOR. In a fit of rage after getting hit with a nightstick, Wisty sets the prison on fire, freeing the kids trapped inside. The Allgood siblings, using powerful magic, turn one of the New Order's lackeys, Judge Ezekiel Unger, into a cockroach. The OWITO explains to Whit 6 prophecies, the 5th being: "The Allgoods shall be executed."
The Allgood siblings pay one last visit to home, which was demolished and replaced with a cornfield. Speaking love, a vision of the house and the parents are revealed, and they transform Whit's journal into a spellbook, and Wisty's drumstick into a magic wand. Wisty's mom also reverts Byron swain into his human form. But things don't go according to plan. Only according to the six prophecies.
