At the start of the American Civil War, German spy Gunter Rohlenheim is sent by Prince Otto von Bismarck to the United States to gather intelligence on the development of an advanced warship. Before Gunter can find his way to his intended target, his nemesis from ten years earlier sends an assassin to neutralize him. Barely escaping death, Gunter is surprised when his investigation uncovers more advanced war technology being developed by the Confederates. Angamar, an enigmatic old scientist, connives to include Gunter into his development of a self-propelled torpedo, and Gunter discovers the reincarnation of his own first engineering project, a submarine. The Confederate submarine experiment evolves into the H. L. Hunley and Gunter, using the alias Sam Miller, is consumed with his desire to become part of her crew. When the Hunley is called up for duty as a blockade breaker in Charleston, South Carolina, Gunter is forced to choose between loyalty to his homeland, the submersible, and an attractive war widow. The forensic reconstructions of the H. L. Hunley's crew sparked the ides of Convergence of Valor. -- Publisher's blurbJoin NH author Guntis Goncarovs at the Toadstool Bookshop in Milford on Saturday, April 20, 2019 at 2 pm where he will present and sign his book.
