Warsprite

Description for WARSPRITE by Jefferson P Swycaffer:

On a quiet night in the desolate hills of Wyoming, two robots from the future crash to Earth. One is a vicious killer, while the other is unarmed, with an ability her warrior brother doe not have. She can think.

The thinking robot, Delta, finds both allies and enemies in her new world. But she can never forget her primary mission. She is programmed to face her murderous brother robot in a final confrontation in a radioactive chamber far beneath the Nevada desert. Which of them is destined to survive?
