The Planet Collector — Laurie Sutton

The super-villain known as Brainiac loves nothing more than adding new data about civilizations to his memory banks--and then destroying those civilizations so the data is more valuable. He has long coveted Metropolis and sought to take it for himself, but the Man of Steel has always been able to repel the robotic villain. But this time, Brainiac has found a sentient Kryptonian ship that collects entire worlds...and led it directly to Earth! Can Superman stop two world-stealing intelligences at the same time?
