E A Carter

She is a prisoner who can alter reality. He is a dead soldier brought back to life as a sentient machine. 2086. In a dying world divided into a luxurious enclave for the super-rich in the far north of Canada and Greenland, and the billions left to survive outside its impenetrable walls, Cassandra's ability to alter reality marks her as a valuable asset to Global Command. Lost in a terrorist attack to the United Freedom Fighters, she is discovered in the seedy underworld of London by an elite soldier who does not learn who she is until far too late, and he too becomes an asset owned by faceless powers.
Resurrected as a near-immortal machine, his first mission is to extract her from London and return her to the ones intent to use her gift to give the rich a second chance at life in a new world. As the world collapses into its death throes, he fights to protect the one he loves, to save her from what is to come, and to give her a second chance .
