This is an interesting science-fiction novel by Michael Crichton about a team of scientists who investigate a deadly disease of extraterrestrial origin which causes rapid, fatal clotting of the blood.
The story starts than a satellite fall into Piedmont in Arizona. A mysterious virus kills 48 people, but two humans survive that. The scientists take the satellite into a laboratory, in order to study it. But the virus has realised. The experts want to wipe out it by a nuclear explosion.
Fortunately, Mark Hall can stop it before it can detonate.

There are four main characters int he novel:
DR. JEREMY STONE: professor of bacteriology at Berkeley; a nobel prize winner
BURTON: pathologist
PETER LEAVITT: anthropologist
DR. MARK HALL: surgeon

In fact I reflected very much about its contents both scientific and humanistic because this subject is quite contemporary, even if this book was written in the ‘50s.
In conclusion, Michael Crichton is an excellent author, after the Jurassic Park, he could write another exciting story. It has many interesting turns and unexpected events. Don’t miss it!
