The epic voyage of the Pathfinder Ship Pegasus continues. After discovering the marvelous ancient technology of the Starlock - a gigantic space station facilitating instant transport across thousands of light years - the crew of Pegasus travels to Aurora, a planet whose intense magnetic fields produce a sky that is a constant blaze of auroras. The major industries of the planet Aurora are pornography, arms dealing, and snack foods. Also, the planet hides a dark and terrible secret that will almost certainly lead to its complete destruction.
