As a pre-med student, I was already interested in the book for its medical plot line. This book turned out to be a book that got my heart rate going as I cheered for the main characters and ached as my favorite character was killed off. Incredible writing. Suspenseful. I actually had to actively slow down while I read so I could savor the story just that much longer. 10/10 would recommend!!

Once again, Robin Cook's writing makes me terrified of hospitals! A page-turner I did not want to out down.

After the first several chapters I skimmed through most of this book. The plot was derivative of previous books. The dialogue was stilted and in particular the attempt at African American slang was just painful to read. I've enjoyed Robin Cook in the past but this was just not good. A real disappointment.

This was agonizing to try to finish. In fact, I never made it to the very end.

Robin Cook has always been close to sophomoric and has managed to write the same book a dozen times with each version paler than the last. With his latest "Host" the unthinkable has occurred - it's worse! The doggerel in this nonsense tome is stupefying, even for Cook. With an uncanny ability to continually underwhelm and create characters as one dimensional as a chalk line Cook has managed to massage page after page with hackneyed dialogue, ludicrous plot lines, impossible science and protagonist vs antagonists that make Boris B and Natasha take on mammoth literary strength by comparison. This has got to be a joke - on all of us...

The latest Robin Cook is amateurish at best. The characters are one-dimensional, the plotting predictable, and the writing is just plain bad. What a waste of money!

Too much medical lingo. Extremely incredulous plot. Boring until the very end.

A horrifying idea is brought to life in this poorly written novel.

Ok read. Same premise as Coma.
