Because some Celtic stories won't be contained in myth.... A little magic has always run in 16-year-old McKayla McCleery's family - at least that's what she's been told. McKayla's eccentric Aunt Avril travels the world as a psychic for the FBI, and her mother can make amazing delicacies out of the most basic of ingredients. But McKayla doesn't think for a second that the magic is real - it's just good storytelling. Besides, McKayla doesn't need magic. She recently moved to beautiful Star Valley, Wyoming, and already she has a best friend, a solo in her upcoming ballet recital - and the gorgeous guy in her physics class keeps looking her way.
When an unexpected fascination with Irish dance leads McKayla to seek instruction from the mute, crippled janitor at her high school, she learns that her family is not the only one with unexplained abilities. After Aunt Avril comes to Star Valley in pursuit of a supernatural killer, people begin disappearing, and the lives of those McKayla holds most dear are threatened. When the janitor reveals that an ancient curse, known as a geis, has awakened deadly powers that defy explanation, McKayla is forced to come to terms with what is real and what is fantasy.
