Zero Day by S. Hussain Zaidi (India's No.1 Crime Writer) - Book Review

Cybercrime is a relatively new concern for law enforcement officials and for us as a layman. As the number of computer owners connected to the internet increases, so too does the opportunity for cyber crime. This book has fast moving narrative that reveals how being interconnected we all are through the internet can be a boon and a bane at the same time. 

Name of the book: Zero Day

Author of the book: S. Hussain Zaidi

Genre: Crime Thriller Fiction


Mumbai is in a state of chaos, and all traffic signals across the entire city have stopped working.

Shahnaz Ali Mirza, head of the Maharashtra Anti-Terrorism Squad, receives an anonymous email claiming it to be a Distributed Denial of Service (DDoS) attack. He quickly puts together a crack team that includes his protege, IG Cybercrime Vikrant Singh, and gets to work trawling the dark web for more information on this mystery attack. However, a move to bring forward the hacker backfires, leading to a second, deadlier attack on Mumbai’s lifeline, the railway system.

It is their first brush with cyberterrorism: a zero-day vulnerability in the Indian government’s system that could bring the country to its knees. Racing against time and investigating a case unlike any other, Mirza and Vikrant face the most dangerous mission of their lives in Zero Day.


S. Hussain Zaidi allows his book "Zero Day" to unfold naturally, with his strong writing, rich characters, vivid detail and excellent pacing all leading to a powerful conclusion that will make you think twice before opening your computer or surfing the Internet. It is certainly is a treat to a read  a good powerful suspense novel, and a very impressive story line. All the characters are strong, stubborn and concerned at the same time. The book talks about politics, corruption and rivalry which is part of every system and how the evil forces are not isolated but are born from the system itself . You will keep turning pages to see just how story unfolds. There are plenty of unexpected twists and turns to keep the reader's interest piqued right up to the last page. This book is intelligently written with a realistic theme.


Zero day is an addictive read that will stay with you for the long time to come. If you are not a computer geek some of the lingo and explanations are going to pass by you but their is enough information and ever developing and terrifying plot developments to keep you riveted to every page. The entertaining story line is linear yet exhilarating and frightening especially since author S. Hussain Zaidi's mastery over terrorism related research is reflected in Black Friday, Mumbai Avengers and other books written on terrorism by him. I think if you are a fan of espionage style books, you will like this one and I have no problem recommending it to people.


A journalist for over 20 years, S. Hussain Zaidi is a writer, publisher, producer, scriptwriter and mentor to new talents. His first book Black Friday, was made into critically acclaimed film by director Arurag Kashyap.  His documentation of the Mumbai mafia in books such as Dongri to Dubai, Mafia Queens of Mumbai, My Name Is Abu Salem are considered some of the finest pieces of investigative journalism. Two of his books has been made into web series, one of which is streaming on Netflix (Class of' 83) and other one is soon to be released on Amazon Prime Video.
