Ben's on a trip to London to meet his mum. But an accident at the Thames Barrier, combined with a tidal surge and a dramatic thunderstorm - and suddenly his trip turns into something totally different as the Barrier is breached and London is flooded. With streets underwater, communications down, rats pouring up out of the sewers and thousands of people in a state of panic, survival becomes a key issue. But as Ben tries to get across London to meet his mother, little does he know that two terrorists have a similar rendezvous . . .
Chris Ryan was born near Newcastle in 1961. He joined the SAS in 1984. During his ten years there he was involved in overt and covert operations and was also sniper team commander of the anti-terrorist team.
During the Gulf War, Chris Ryan was the only member of an eight-man unit to escape from Iraq, where three colleagues were killed and four captured. It was the longest escape and evasion in the history of the SAS. For this he was awarded the Military Medal.
For his last two years he was selecting and training potential recruits for the SAS. He wrote about his experiences in the bestseller The One That Got Away, which was adapted for screen, and since then has written three other works of non-fiction, fourteen bestselling novels and a series of childrens' books.
His latest series of novels - the Extreme books take you even further into the heart of the mission with more extreme action, more extreme language and more extreme pace. Like Call of Duty or Medal of Honor, you'll feel part of the team.
He lectures in business motivation and security, and is a consultant for a security organisation. You can find out more information on Facebook at www.facebook.com/ChrisRyanBooks. You can also follow Chris on Twitter @exSASChrisRyan
