The Defender is a near-indestructible robot whose brain contains the
extensive scientific and military knowledge of five men. Created by the
smart, beautiful Megan Drake, the Defender longs for Megan's love as he
works to implement Megan's dream: planting and nurturing the human race
on far-off planets. Along the way he battles previous colonizers--human
and robot alike--and discovers the limits of being indestructible.
