One simple yawn is all it takes for teenager Daffodil Lane to unknowingly breathe in a wandering soul and swallow it, trapping it in her stomach. To the rest of the world, the soul sounds like a rumbling tummy, but horrified Daffodil hears a voice insistently demanding to be released. She travels back in time more than 100 years in an attempt to rid herself of the voice and to reunite it with its body, but the repercussions of her journey reverberate through the years, affecting the lives of people in both the Victorian times and the 21st Century.
