This a bit of departure from Tess Gerritsen's usual crime that I read, but it was an unputdownable - I read it in 8 hours. I loved the two parallel stories. Lorenzo's story is set in an increasingly violent and fascist Italy during the second world war and Julia's in modern day America. Their lives collide through time through a piece of unpublished music called Incendio ... there are some heartbreaking moments.
