I finished Playing with Fire by by Tess Gerritsen a few days ago. I really enjoyed it. It was one of those two-stories-in-one books - a story in current time connected to a story in the past. In the current time, a violinist buys a book of old gypsy music when she performing in Italy. In the book is a piece of handwritten music that seems to have strange effects on her child. The story of the past takes place during WWII in Italy. What was really interesting is that the author wrote a piece of music - presumably the music from the novel. I purchased it for $1.25 & it's good. Different & it goes dark, but I liked it.
Now I'm reading The Immortal Life of Henrietta Lacks by Rebecca Skloot. It's a fascinating non-fiction about how this woman's cells were taken from her during a cervical exam & how unique they are. Yes, I used the word are, because they are still alive. Here's a short version of the medical side of the story & something about the book below. I'm only about a 1/3 of the way through but it's really interesting. There is a human element too. It's not all medical.

I'm going to check out The Power of the Dog. Sounds interesting.
