The premise: At some point in the near future geneticists come up with an inexpensive way to for parents to be able to engineer children to fit their personal specifications. For a decade it became a world wide fad producing millions of genetically modified children but after the fad faded and many of these children started hitting puberty they began to develop extraordinary abilities leading to fear and prejudice against these children that people took to calling splicers. Some grew angry with the world over their treatment and became hostile forcing the government to start recruiting their own splicers to police them.
