After the Earth was destroyed by ruthless machine intelligences known as the Cold Minds, the remnants of the human race sought refuge among the Hidden Worlds. Now, after six centuries, word comes that humans may have survived in the most dangerous hiding place of all—Earth’s solar system. The Cold Minds have returned and humanity’s very existence is at risk—the fight is not going well for the Hidden Worlds. But now renegade pilot Linnea Kiaho has discovered that free humans still survive in Earth’s solar system, the center and fortress of the Cold Minds.
With her fellow pilot Iain sen Paolo, Linnea embarks on a dangerous journey to Earth’s system, risking their lives in hope of discovering how humans have survived there. But what she finds is a secret so shocking, a truth so dangerous that it may save the Hidden Worlds—or shatter them forever.
