The narrator is really annoying

First time reader (listener) of Robin Cook, excellent book!!! I've been in medical profession of some sort since early 1980's, so I enjoyed the storyline! Some parts actually had me clinching my teeth, and I even yelled out "run faster" during the climax part of the book! & the narration is great, he's very good at keeping characters different! I've started next Robin Cook book & same narrator, so right away you continue your relationship with flow-over characters from last book! Thank you for that!!!
