It's about four hundred years hence. Earth has founded about three hundred colonies scattered around the wider universe and has come into contact with about four dozen other species. As you can imagine friendliness varies a lot and there were a lot of wars fought because of real estate, resources, simple miscommunication and human being tasty. So the default interstellar government the Inter-System Authority (stupid name?) decided to build a force of special operatives. They opted to make use of two relatively recent scientific advances. First was the perfection of genetic engineering, and second was mind transference. Mind transference was originally formulated as life extension. The elderly could become regain their youth by having their conciousness moved into a specially created clone. The technology hadn't yet been released to the public since nobody could figure out how to deal with the probable over crowding it would cause. But the Inter-System Authority had thought up a socially "safe" use... Basically the idea was to offer parents of intelligent, but terminally ill or severely disabled children a cure. Basically the deal was the kids would undergo mind transference. But not just into healthy bodies, but into massively genetically enhanced ones. Then the parents would relinquish most rights to their child and he or she would be carted of for years of special forces training. The rationale was children would be able to adapt to the new bodies as they grew up, and that their conditions would make them view the change as a gift and instil loyalty. The story would focus on six of these children growing up together. They're recruited at the age of eight. Also no they don't see combat (at least they're not supposed to) until they're about twenty. Do intend to explore the ethical ramifications (of which they're is obviously many) of the whole thing. First "important" question is what effect would transplanting the mind of say a child with Down's syndrome into one of these bodies, which of course have perfectly healthy brains.
