I was provided an advanced reader copy of this book by Netgalley and the publisher, in turn for an honest review. Many of you may have heard of Tess Gerritsen because of her "Rizzoli and Isles" series. This book was not from that series but just as good; in fact I have never read a book with a plot similar to this one.
Violinist Julia Ansdell is traveling in Italy when she happens upon a handwritten piece of street music in a music book she bought. It is like nothing she has ever seen or played before; when she plays it she is entranced. She finds though that when she plays it her daughter acts strangely, seeming to do almost evil things. She researches the origins of the music, as well as taking her daughter to doctor after doctor, but everyone seems to think Julia is the crazy one. Her research takes her back to Italy. Shortly after she arrives there she finds people seem to want her dead. But why?
