The first edition of one of the last and most interesting continuations of the Arthurian cycle. An expansion of the story of Tristan and Iseult, Ysaie is the story of their son, born to the couple just before their deaths and a few years before the collapse of the Arthurian kingdom. The romance deals with the troubled years after Arthur, and the efforts of Ysaie and his own son Marc to combat evil in post-Arthurian Britain.
