Abby O'Malley is a girl who likes things to make sense. School makes sense, and her best friend Paige makes sense (most of the time), but Abby's flighty mother never makes sense. Abby's mom seems to think that she and Abby are descended from a line of witches, and that they have special powers—psychic powers that don't make sense at all. The problem is, Abby knows that she can do certain things that other people can't. Sometimes, when she holds an object in her hand, she's overpowered by sounds and pictures that show where the owner is and what he or she is doing. Abby thinks of this as her "magic nation," because that is what her kindergarten teacher told her it was called. Now 11, Abby has an inkling that her teacher may have been saying it was her "imagination," which unfortunately, she knows it is not. Now some things are happening in her mother's detective agency—cases where Abby's magic nation thing might come in handy. But does Abby want to admit that such a sensible girl could have such an unsensible power?
