Adrift in a raft after a terrible shipwreck, ten strangers try to survive while they wait for rescue.

After three days, short on water, food and hope, they spot a man floating in the waves.

They pull him on board - and the survivor claims he can save them.

But should they put their trust in him?

Will any of them see home again?

And why did the ship really sink?

The Stranger in the Lifeboat is not only a deeply moving novel about the power of love and hope in the face of danger, but also a mystery that will keep you guessing to the very end.
