Crossover


Joel Shepherd - 2001
    Cassandra is an experimental design — more intelligent, more creative, and far more dangerous than any that have preceded her. But with her intellect come questions, and a moral awakening. She deserts the League and heads incognito into the space of her former enemy, the Federation, in search of a new life. Her chosen world is Callay, and its enormous, decadent capital metropolis of Tanusha, where the concerns of the war are literally and figuratively so many light years away. But the war between the League and the Federation was ideological as much as political, with much of that ideological dispute regarding the very existence of artificial sentience and the rules that govern its creation. Cassandra discovers that even in Tanusha, the powerful entities of this bloody conflict have wound their tentacles. Many in the League and the Federation have cause to want her dead, and Cassandra’s history, inevitably, catches up with her. Cassandra finds herself at the mercy of a society whose values preclude her own right even to exist. But her presence in Tanusha reveals other fault lines, and when Federal agents attempt to assassinate the Callayan president, she finds herself thrust into the service of her former enemies, using her lethal skills to attempt to protect her former enemies from forces beyond their ability to control. As she struggles for her place and survival in a new world, Cassandra must forge new friendships with old enemies, while attempting to confront the most disturbing and deadly realities of her own existence

Death's Head


David Gunn - 2007
    David Gunn is loaded–and he shoots to kill.At the top of the galactic pecking order is the United Free, a civilization of awe-inspiring technological prowess so far in advance of other space-faring powers as to seem untouchable gods. Most of the known universe has fallen under their inscrutable sway. The rest is squabbled over by two empires: one ruled with an iron fist by OctoV, a tyrant who appears to his followers as a teenage boy but is in reality something very different, the other administered by the Uplifted, bizarre machinelike intelligences, and their no-longer-quite-human servants, cyborgs known as the Enlightened.Sven Tveskoeg, an ex-sergeant demoted for insubordination and sentenced to death, is a vicious killer with a stubborn streak of loyalty. Sven possesses a fierce if untutored intelligence and a genetic makeup that is 98.2 percent human and 1.8 percent . . . something else. Perhaps that “something else” explains how quickly he heals from even the worst injuries or how he can communicate telepathically with the ferox, fearsome alien savages whose natural fighting abilities regularly outperform the advanced technology of their human enemies. Perhaps it is these unique abilities that bring Sven to the attention of OctoV.Drafted into the Death’s Head, the elite enforcers of OctoV’s imperial will, Sven is given a new lease on life. Armed with a SIG diabolo–an intelligent gun–and an illegal symbiont called a kyp, Sven is sent to a faraway planet, the latest battleground between the Uplifted and OctoV. There he finds himself in the midst of a military disaster, one that will take all his courage–and all his firepower–to survive. But an even deadlier struggle is taking place, a struggle that will draw the attention of the United Free. Sven knows he is a pawn, and pawns have a bad habit of being sacrificed.But Sven is nobody’s sacrifice. And even a pawn can checkmate a king.From the Hardcover edition.
