I thought that this story about two sisters, one to be found to be a math genius at the age of 12 was just o.k. (If not a little bit strange). It just wasn't one of those books that I couldn't put down. I found myself annoyed about the main character's reaction to certain things, and also found myself wanting to hurry and finish it just to get it over with.
Another wonderful story from such a talented writer!
