The 4th book in the series and again very well researched. Intriguing storyline and our hero Thomas rises to all challenges. I particularly find the accounts of his surgeries well written. This and the previous book in the series are the best so far. The stories are unique and each more fascinating than the last. This one ends on a cliffhanger and I now can't wait for book #5!
