Query: Very Good

This book was thrilling and very interesting. I have read lots of Mystery/Thrillers but not relating to anything to do with the medical business. Well written and one of the books I couldn't wait to finish to find out what would happen. Characters were good and it was easy to follow with no confusion of who is who. Sometimes there are too many characters and it can get a little confusing. I do recommend this to someone looking for a good thriller.
