Maren Malone, a half Irish, half Native American 18 year old girl, has kept her ugly secret--her four breasts--under wraps, so to speak. Everything changes when her father dies and her mother convinces her to go up to the White Earth Reservation to learn about her roots. Maren reluctantly goes and gets to know her grandfather, Blackhawk Malone. He presents her with a special wolf pup from the "smart ones" stock whom she names Moonbaby. Maren comes to love the culture that she had always dismissed as weird, and discovers that she is special--not just a freak as she had always believed. Her family and only one other on the rez are the only ones left that carry the "changeling" gene, an ancient mutation of the Ojibwe tribe. Maren learns to make the "hard but right" decisions, discovering her true bloodlines, and all she must sacrifice--or not? Afraid and doubtful of her responsibility, it is her wolf, Moonbaby, that shows her who she really is. When she discovers love, she knows what she must do, no matter what the cost. Will Moonbaby show her what it is like to be real and true to oneself, one's family, one's tribe? Or will she take the easy way of the human--dishonesties, manipulations, . . . self above all?
