For seven years bad luck has followed Ivy around like a dog on a leash. Her father disappeared. Her mother is a washed-up beauty pageant winner. Her aunt Viola has died. Viola did leave Ivy and her mother a house on Gumm Street, but it's not much of a house, and Ivy's next-door neighbors (bookish Pru, stuck-up Cat, and wannabe adventurer Franny) are worse than unfriendly. But then a mysterious pair of ruby red slippers turn up, and the four girls are swept away - not to Oz but to the jaw-droppingly strange lands of Spoz, Spudz, and Ooze, where they are pursued by the fashionably mad Cha-Cha Staccato - who bears a frightening resemblance to a certain wicked witch.
This is a really interesting book. I enjoy grade school or YA books occasionally, and I will listen to this one again. If you enjoyed the books written by E. Nesbit, you will most likely enjoy this. Colleen Delany is one of the best Audible narrators; she reads at the perfect speed and is able to put a unique voice to each character.
