Ten men adrift on a lifeboat. Only one will live to tell the tale.

The sequel to This Time Tomorrow.

June 1944, World War Two: a convoy ship is torpedoed and sunk by a German U-boat. Most on board are killed but ten sailors manage to clamber aboard a lifeboat.

Robert Searight emerges as the sole survivor. Traumatized by the experience, he returns to his English village to recuperate. His only task is to return a dead friend's wedding ring to Joanna, the man's widow. But Joanna is nowhere to be found.

His return to the village brings back the heartache he felt when, a year previously, his fiancée, troubled by her own past, broke off their relationship.

But ultimately, it's his own dark secret that he must confront before he can come to terms with his broken heart and the trauma of having survived The Unforgiving Sea.

A sequel to This Time Tomorrow, The Unforgiving Sea is, on its surface, a tale of murder, survival and loss, while at its core we find a story of deep love, loyalty and forgiveness.

A masterpiece of story telling.

Rupert Colley is the founder, editor and writer of the bestselling 'History In An Hour' series of ebooks and audio, published by HarperCollins. The Unforgiving Sea is his seventh work of historical fiction.

Historical fiction with heart and drama.
