After completing his time aboard the Federation's Survey Service Crusier, Pathfinder, John Grimes is denied a promotion but given command of a small Serpent Class Courier called Adder. His first assignment is a relatively unimportant one - to ferry the mysterious Mr Alberto to the planet Doncaster.

When he is invited back to her apartment to read some literature on the League of Life, the unexpected happens (again).
