Heaven's fall

Humanity is facing its greatest challenge. The alien Reivers have conquered our world. 20 years earlier, extraterrestrials came to Earth, and abducted humans, stranding them on a spacecraft named Keanu. They came seeking our help against the Reivers who had overrun their home-world. But they brought the Reivers to us, carrying their contagion from the stars. Reivers are now preparing to destroy Keanu. Rachel Stewart will leave the ship to lead Earth's last rebels in a bid for freedom.
