We Lost Earth

Gate World is connected to Earth through a star gate in geosynchronous orbit. The Gate World colony produces amboria, an invaluable mineral for Earth, so Earth treats the dictatorship in the colony as a resource, ignoring brutal suppression of human rights. Anything is tolerated to get the amboria. A young woman leads a revolution that literally severs ties with Earth by destroying the star gate. Gate World is now free but the colony almost dies without external support. This is a story of courage, sacrifice, and the ultimate test of human endurance, first against a ruthless dictatorship, then against nature itself.
