Soldier, Ask Not

When mankind burst into the stars, the human psyche splintered - and humanity became many species, each a specialized overdevelopment of a single trait. Tam Olyn was a trained new observer from Old Earth - a complete man. To him the conflict between the fissuring worlds was at first a challenge, then a personal vendetta. The Friendlies were his enemy... in them blind fanatical faith had become an all-abiding obsession. The Dorsai were warrors, born and bred, but they had not used their talents for self-glory but had placed them - for a price - at the service of others. And when these two driving destructive talents of humanity met head on, Tam Olyn had a plan of his own for which cosmic humanity was not prepared. (from the back cover of the 1975 DAW Books edition)

Hugo Award Winner

If the title of this book should seem familiar it is because one-third of it, as a novella, won the Hugo Award, the Pulitzer Prize of Science-Fiction. This one-third has not been expanded; rather it has been added to the remaining two-thirds of the complete story to form this most unusual, exciting and never-before-published novel – Solder, Ask Not."
