Through brutal tactics and aggressive terraforming, the Daughters of Mars had driven their parent species to the brink of extinction; the iron oxide bomb did the rest. Orphans by their own hands, masters of a dead planet, and sterile from birth, they now turn their intellects-- vast, cool, and unsympathetic-- towards other planets, in search of some strange new destiny. In recognition of their valiant service during the Genetics War, the Imperatrix and her Sisters of Battle are assigned the nearest fertile planet. But sixty-five million years in our past, the dinosaur-dominated Earth proves to be far from the paradise they were promised, and natives have no use for honor and glory. After the first day, only twelve Daughters remain... Among that number are brave Jarissy; sly assassin Danalee; ambitious and seething Quasha; the mysterious Petara; the manipulative sociopath Ress; and the beautiful Nerrine, who is far stronger, and more dangerous, than anyone knows.
