This "new" Roger Zelazny work was finished posthumously with the help of his coauthor and friend, Jane Lindskold. Unlike some after-the-fact "collaborations," this one has Zelazny written all over it. It's a typical tale from one of science fiction's greats, a world-spanning story that deals heavily with mythology and the ability to cross between two realities. In this case the realities are the real world, Verité, and the virtual world, Virtù. When Donnerjack--one of the architects of Virtù--loses his lover Ayradyss, he makes a pact with Death to return her from the dead. In return, Death demands their first-born child, who will be the first baby born from a Verité/Virtù union, and a force to be reckoned with in both worlds.
