A metal highway under the sea, a rival to the massive powdered-coal-burning flying machines that dominate the transatlantic route, is no longer a dream. Captain Augustine Washington, the engineer, and his team of navvies are driving the tunnel across the Atlantic in an historic feat of construction.

For Gus, a descendant of the infamous George Washington, executed after the Battle of Lexington, this is the opportunity to redeem the family name. But Gus's appointment has resulted in the implacable hostility of his employer, Sir Isambard Brassey-Brunel, who orders his beautiful daughter, Iris, to break off her engagement to Gus. And there is a sinister plot to destroy the tunnel - and Gus himself.

Harry Harrison's delightful parallel-world novel is set in the heyday of a British Empire that never lost its American colonies and is still driven by the spirit of Victorian enterprise and a Victorian code of honour. Highly enjoyable and satisfying, A Transatlantic Tunnel, Hurrah! is Harry Harrison at his idiosyncratic best.
