The only way to hunt down a killer is to become one…

After two long years spent in a secret British prison, Nadia Laksheva is suddenly granted her freedom. Yet there is a dangerous price to pay for her release: she must retrieve the Russian nuclear warhead stolen by her deadliest enemy, a powerful and ruthless terrorist known only as The Client.

But her mysterious nemesis is always one step ahead and the clock is ticking. In 37 hours, the warhead will explode, reducing the city of London to a pile of ash. Only this time, Nadia is prepared to pull the trigger at any cost…

The deadly trail will take her from crowded Moscow to the silent streets of Chernobyl, but will Nadia find what she is looking for before the clock hits zero?

37 Hours is the follow-up to 66 Metres and the second in the series to feature Nadia Laksheva. Housekeeping first, the story of 37 Hours picks up 2 years after events in 66 Metres. There is clear reference to what has already gone before and I am certain that reading the books in order would be advantageous. However, I have not read the first book and I had a blast reading 37 Hours so while it may be advantageous it is by no means essential – 37 Hours can stand alone as a cracking story.

This was an adventure thriller where events zip around the globe and the stakes felt so high that the tension was ever present. Nadia Laksheva is in prison – two long years of captivity and as 37 Hours opens we see her in her cell contemplating her situation. But the story begins just as Nadia is offered a chance to walk free – assuming she will assist with a mission which is considered to be of vital importance.

Straight into the action from here and I was sucked into a story which kept me hooked. Nuclear missiles lost at sea means Nadia has to dive with a team of “experts” to make them safe. The underwater scenes are brilliantly detailed and had me flashing back to the first time I saw Thunderball – the dark (almost claustrophobic) tension as the hero – in this case Nadia – places her life on the line and faces unexpected challenges.

The story shifts location and there are more underwater scenes to enjoy and a new danger to be faced. No spoilers, however, the underwater cave scenes chilled me. Gotta love when a book does that!

JF Kirwan has done a brilliant job of keeping 37 Hours a tense, tight and wickedly entertaining adventure story. Nadia is a feisty and likeable lead and she faces more than her fair share of peril during the course of events.

I really do not want to give away too much of the story but with a nuclear threat, a sinister “bad guy” calling the shots, exotic locations and Russians, Germans and Brits keeping that global feeling running through the book – this feels like the Summer Blockbuster you don’t want to miss.
