Stuck at a crossroads between her looming future and the alluring call of an escapist slumberland, Jessi Hugson finds herself in a dream that's unlike anything she's ever encountered.
Jessi Hugson finds herself on the abandoned farm of Dorothy Gale in the midst of Kansas. A storm follows and soon Jessi and her cousin Wallace find that Oz isn't what it used to be.
Jessi and Wallace make their way to the Emerald City in hopes that Princess Ozma can get them home. Unfortunately, the Emerald City is a little worse-for-wear and Ozma, like Dorothy, is missing…
With Jack Pumpkinhead proving to be less-than-helpful, Jessi, Wallace, and Lurline head to Gillikin country to seek out the council of the Good Witch of the North.
Having learned that the last person who saw Dorothy was Tik-Tok, the mechanical butler, Jessi and her friends travel to meet his maker, Mr. Tinker, who lives in a steampunk city on the moon.
The gang find themselves in a network of treehouse libraries as they recover from the poppy attack.
