Another fine sci-fi, fantasy read for me. I seem to be on a roll lately. THE GLASS HARMONICA is a gentle version of the genres.
One half takes place in 1760 England. This is the time of Benjamin Franklin spending time in both England and the colonies. He finds a young Irish girl, Eilish Eam, playing her water glasses on the street for money. He takes her in to help him with a new invention of his, the glass armonica. She plays for Franklin and his cronies and then for royalty.
Half of the story takes place in the near future of 2018 Seattle. This half of the story has the main character of Erin Rushton. She is a classical musician, playing the modern version of the glass armonica, for audiences all over the world.
Both girls in both times find themselves 'haunted' by the other's presence from time to time, especially in times of stress. Erin goes in search of her 'wraith' and discovers more about her own sense of self in the search.
Warm and wonderfully written. Four fascinating beans.
