Sub talFAR off the coast, in the perilous waters of the Norwegian Sea, every submariner's nightmare comes true. The USS Tulsa lies stranded at the bottom of the ocean: her crew alive, her pressure hull still miraculously intact... but with the clock ticking mercilessly towards doom.

With only days to live, the crew's only hope lies with the Russian men whose treachery sank their ship. Will the Russians inform the US and face their wrath, or keep quiet and hope that the Tulsa is never discovered?

Former Royal Navy Officer James Francis marks his fiction debut with this thrilling, chilling race against time. Spanning continents and emotions with a cool, compelling

skill, this international narrative will have you reading long in to the night.

Drawing on his experiences in the Falklands Conflict, Francis crafts realism from this impossibly tense tale. Danger's Hour (Published by Simon and Schuster at £6.99).
