ER. The Oral History, by Lynette Rice

 
With numerous references and anecdotes about Michael Crichton, this is a must-read for ER fans!

I hereby would like to honor Leland Orser, who played Dr Lucien Dubenko from seasons 11 to 15, but surprisingly was not included nor mentioned in this book. I think he played a sufficiently important role to deserve to be included.
