Cassilde Sam is a barely solvent salvage operator, hunting for relics in the ruins left by the mysterious Ancestors—particularly the color-coded Elements that power most of humanity’s current technology, including the ability to navigate through hyperspace. Cassilde is also steadily fading under the onslaught of Lightman’s, an incurable, inevitably fatal disease. She needs one last find big enough to leave a legacy for her partner and fellow salvor Dai Winter. When their lover and former colleague Summerlad Ashe reappears, offering them a chance to salvage part of an orbiting palace that he claims contains potentially immense riches, Cassilde is desperate enough to take the gamble, even though Ashe had left them both to fight on the opposite side of the interplanetary war that only ended seven years ago. The find is everything Ashe promised. But when pirates attack the claim, Cassilde receives the rarest of the Ancestors’ Gifts: a change to her biochemistry that confers near-instant healing and seems to promise immortality. But the change also drags her into an underworld where Gifts are traded in blood, and powerful Gifts bring equally powerful enemies. Hunted for her Gift and determined to find Gifts for her lovers, Cassilde discovers that an old enemy is searching for the greatest of the Ancestral artifacts: the power that the Ancestors created and were able to barely contain after it almost destroyed them, plunging humanity into the first Long Dark. Haunted by dream-visions of this power whispering its own version of what happened, Cassilde must find it first, before her enemy frees it to destroy her own civilization.
Author

Scott studied history at Harvard College and Brandeis University, and earned her PhD. in comparative history. She published her first novel in 1984, and has since written some two dozen science fiction and fantasy works, including three co-authored with her partner, Lisa A. Barnett. Scott's work is known for the elaborate and well-constructed settings. While many of her protagonists are gay, lesbian, bisexual, or transgendered, this is perfectly integrated into the rest of the story and is rarely a major focus of the story. Shadow Man, alone among Scott's works, focuses explicitly on issues of sexuality and gender. She won the John W. Campbell Award for Best New Writer in Science Fiction in 1986, and has won several Lambda Literary Awards. In addition to writing, Scott also teaches writing, offering classes via her website and publishing a writing guide. Scott lived with her partner, author Lisa A. Barnett, in Portsmouth, New Hampshire for 27 years, until the latter's death of breast cancer on May 2, 2006.
