Sector General novels are almost always nice enjoyable reads. White created a kind universe in these books, with medical mysteries and alien perspectives to pull you into the plot. This one introduces Nurse Trainee Cha Thrat who is a Warrior/Surgeon on her home planet. Her ethics get her into all kinds of interesting trouble in this novel as she tries on various roles in the Sector General hospital and is tossed out time and time again after managing to do some good in a highly disagreeable manner for the ethical staff of Sector General. "Code Blue: Emergency!" is collected with "The Genocidal Healer" into the Sector General omnibus called "General Practice". Like episodes of House M.D., you will enjoy these books immensely then forget most of the finer details of the medical mysteries as time goes by, so they are good for a reread.
