This is different from Crichton's other books, but still is a gripping plot. This book is a look at what might happen when doctors start trying to change parts of the mind physically. Excellent book!

Another good Crichton read. Although it's dated (early 70s), it still manages to capture the imagination. Better than average "what if" book.

Lags a bit at time, but a pretty cool book in all.

Set and written in the early 70s with themes around artificial intelligence, psychology, and mental disorders. Neat to flash back to a time when computers weren't quite omnipresent, but now it seems outdated. Not bad and a relatively short novel.

2 stars out of 5
