Will I love Ultimatum?

The fast pace of this thriller is fuelled, not only by the speed with which the plot unfolds and its high level of action, but also by its extremely short chapters. The way it keeps the adrenaline pumping all the way through made it almost impossible to put down before the end. The book's exciting conclusion is tense, surprising, somewhat shocking, and very well written. Overall, this is certainly one of the best thrillers I've read for quite some time.

A best seller from BBC security correspondent Frank Gardner.

MI6 agent Luke Carlton is on a mission to uncover a secret cave system at a military complex south-east of Tehran, in which scientists work round-the-clock on a banned nuclear device, at the behest of ultra-conservative Iranian Revolutionary Guards.

Gardner himself was ambushed and left paralyzed by Islamist gunmen, while on assignment in Riyadh. This is a rare thriller set in Iran, although the action also extends to neighbouring countries such as Armenia.

Fast-paced, well-written, and authentic. What more can you ask for?
