Ever since she escaped the city within the Wall, Lark Ainsley's wanted one thing: to find her brother Basil. She's always believed he would be the one to put an end to the constant fear and flight. And now, hidden underground in the chaotically magical city of Lethe, Lark feels closer to him than ever. But Lethe is a city cowering in fear of its founder, the mysterious Prometheus, and of his private police force. To get the truth about what happened to Basil, Lark has no choice but to face Prometheus. Facing her fears has become second nature to Lark. Facing the truth is another matter. Lark never asked to be anyone's savior. She certainly never wanted to be anyone's weapon. She might not have a choice

Seaton and DuQuesne are mortal enemies who must now fight on the same side for the good of humanity. Seaton is on constant alert for Duquesne’s double-cross. Skylark DuQuesne was the final novel in the epic Skylark series by E. E. Smith. Written as Smith’s last novel in 1965 and published shortly before his death, it expands on the characterizations of the earlier novels (written 1919 – about 1938) but with some discrepancies (some of which may relate to unwritten background developments). The most significant point is that Dr. Marc DuQuesne, the major villain of the three previous novels, is shown to have matured, reformed, and offered a chance at what amounted at pardon for his prior crimes against the heroes. Skylark DuQuesne was first serialized in IF Worlds of Science Fiction beginning in June 1965 before being published in 1966 by Pyramid Books. Nominated for Hugo Award for Best Novel in 1966
