In a world devastated by nuclear holocaust, Snake is a healer. One of
an elite band dedicated to caring for sick humanity, she goes wherever
her skills are needed.
With her she takes the three deadly reptiles
through which her cures are accomplished: a cobra, a rattlesnake, and
the dreamsnake, a creature whose hallucinogenic venom brings not
healing but an easeful death for the terminally ill.
Rare and
valuable is this dreamsnake. When Grass is wantonly slain, Snake must
journey across perilous landscapes to find another to take its place...
