Could not put down.... Read in two days...fast pace technology /stock market finance thriller with several turns. Harris is an excellent story teller..

Robert Harris is a fabulous writer, and never disappoints. His stories of Rome are masterpieces, and, like Ghost Writer would all make fine films. Fear Index would as well. The book is not his best because things happen that aren't quite right, a bit odd as the main character manages to get in and out of situations too easily. Where are the security cameras at his house, for instance? Why does his security guard not follow him when he leaves the building ? As the clever plot unfolds, I found the book reading more like a Michael Crichton novel where things keep going wrong that shouldn't. At the same time, I could not put it down! Intelligent and perfectly researched, it is a thriller. In the end I was reminded of the great line from 2001 A Space Odyssey: "I'm sorry, Dave, I can't do that." Harris is a favorite of mine as many friends who receive signed copies from me can attest. I eagerly await his next.

This is a book Robert Harris should not have written. All his excellent qualities as a writer turn against him in this book. The Fear Index is a disappointment, too much excellent research, too little literature. One can read an encyclopaedia instead.

This book is absolutely amazing!!!!!! from the very first page you can put it down. It's humorous, romantic, and is absolutely talking about real life problems that are current and that human kind has faced. Great Book Great Job Robert Harris

I could not put this book down. Excellent , Jim walls

Excellent book! I read it in under 24 hours, I couldn't put it down. The way Harris blends the techno-thriller genre with modern financial market trading is fascinating.

Books is really great. I sometimes thinking about the consequences of fully automate the human jobs. The book is giving answer what could have happen then. Book is written with good language, very smooth in read and with great idea. Strongly recommend to read.

Exciting page turner that kept me engaged for hours. Interesting premise that sheds some light on current financial events. Also captures how big money can take on a Life of its own. I think I will stay invested in real things. The future investor will not own his investments. The future investor will be digital. The investor of the future is watching you now.

Aside from one or two pretty implausible moments, it was great. I couldn't put it down.

this book is so unlike to all other Robert Harris books, one can not believe it to be written by him. Lengthy, without suspense and surprises, coming to a dead end. Waste of time and dime.
