The Cold Minds

After the Earth was destroyed by ruthless machine intelligences known as the Cold Minds, the remnants of the human race sought refuge on the Hidden Worlds. Now, after six centuries of safety, the horrors of the past have returned to finish the extermination.
 
Renegade jump pilot Iain sen Paolo and Linnea Kiaho know that the Cold Minds have found humanity again. To fight back, they need to recruit jump pilots. But the secretive Pilot Masters guard their secrets—and their ships—jealously. They refuse to admit that the Cold Minds have returned, or that anyone not of their number could possess the ability to fly a jump ship. Now, Linnea must prove the Pilot Masters wrong.
 
On the run, and desperately searching for allies to oppose the Cold Minds, Linnea and Iain face near impossible odds. But they know that somehow, someway they must succeed—or humanity itself will become extinct.
