Amazon.com Book Description (ISBN 0884046532, Hardcover)

Ole Doc Methuselah was the name by which he was known on a myriad of scattered planets, for he was the most famous member of the most elite organization of the cosmos, the Solders of Light. But he was no soldier in the military sense, for the enemies he fought were disease, corruption and the warped psychology that spread in the isolation of mankind's lost planetary colonies.

Encountering double-dealing, mutation and the unexpected, Ole Doc and his unique, multi-armed companion Hippocrates share a series of astonishing adventures in their unending journey through the trackless galaxies.
