Somewhere around the early eighteenth century, young Will Harvell joins a sea voyage in search of a mariner's missing son which gradually finds itself drawn towards an ancient and indescribable terror of the ocean in E. H. Visiak's classic novel, which returns to print featuring a new introduction by horror expert Aaron Worth.

Combining elements of Conradian sea adventure with Atlantean mythology and a uniquely unsettling brand of metaphysical, sublime horror--all delivered in Visiak's high literary style--Medusa remains a distinctive, influential and still exciting work in the history of early twentieth-century weird writing.
