Pru, Franny, and Cat all live on the same block. Franny longs for adventure, Cat supposedly has ESP, and Pru knows how to do a cartweel but would rather make a long list of safety tips. But when a new girl Ivy moves into the haunted house at the end of the block with a long line of bad luck trailing behind her, and the piano teacher mysteriously disappears, and Cat talks to a man floating in a hot air balloon with the word Oz written on it and woman named Cha-Cha shows up things get... complicated.

I know this might not be the best description of the book, but it's really good, so take my word and read it!
