Tess Gerritsen keeps you on the edge of your seat the entire book. Why are young boys having anger issues and murdering their families? This book is entertaining and though provoking!

Holy Cow. This was one of the best books I've read from Tess! I read this book in less than one week. I was so, how do I want to put this, emotionally attached. I was almost in tears during multiple parts of this book. Tess went into so much detail I felt like I was right there in the pages. I would recommend it!

Tess Gerritsen is a great writer. And she wrote some great books (e.g. The Surgeon!). Unfortunately, she is wave riding her success by a high volume output. This just-in-time production of one book after the other still reflects solid craftsmanship (why she is a great writer). But here again, she is far away from her best. Let's hope that she will trade time for content once again in the future. "Bloodstream" is based on a very simple story, which is drawn very much in length. If it would have been one out of five stories in one book, it would have made up for a qualified addition. But to take it as the only base for a whole book, needs a lot of filling material. So the book is good as a start for a good night's sleep. But certainly it's not a page burner/turner.

Her writing style reminds me of Robin Cook and Michael Chriton medical thrillers. They were very intriguing and the use of her medical expertise entwined in storyline kept me hooked. Another good one of hers was Life Support.
