Alpha Tribe

American President, Maria Alatorre, realizes two things. The first is that Humanity's tribalism is the reason for its failure to unite in the face of the Fahr threat.  The second is they can not rebuild the Earth's damaged infrastructure in time to save most of the planet's population from starvation. Billions will die. But will humanity survive?  She embarks on an ambitious program to re-engineer tribalism out of the human species using genetic engineering. This give it a fighting chance should the Fahr reappear.  But can she do this in an infrastructure-shattered world where tribalism, in the form of hostile well-armed militias, has a new life?

Honi Kalawai'a is spunky teenager paralyzed from the neck down. On the day the Fahr change the Earth, they too change her. Honi discovers that she can now regenerate her spinal column.  She learns that her improved nervous system also allows her to interface with and be enhanced by computers.  Soon she finds her computer-enhanced mind involved in Alatorre's efforts to rebuild humanity.  When they find a Fahr database, Honi attempts an interface with that.  What happens next is well beyond enhancement.
