Interran - Zeta Trilogy, #2

Zeta Telson has found her purpose: defeating the Specters! Those absolute black, ameboid aliens with an appetite for abduction have haunted the Surya system for long enough! When things don't go as planned at the Guardian Embassy, Zeta must find another path to her goal. Luckily, Pip-Rho and Pip-Tau have just what Zeta needs. They're running this year's EoE sponsored project - Interra, a medieval fantasy gameworld employing a clever tactic to discover solutions to the Specter problem.
As Interrans, the Telson party battles the Specters' in-game analogs, the wraiths, revealing the path to victory in the real world. But how far will Zeta go to reach her goals? Will she forego the promise of love for the sake of vengeance? Nobody ever said fighting aliens would be all fun and games. Interran is Rob Grafrath's second novel. It is the second novel in the Zeta Trilogy, and the second work of the Sapiens? Universe.
