In 2045, the climate crisis has pushed civilization to the brink of nuclear war. Trillionaire space magnate John Rook leads a desperate escape to the nascent Mars colony. But when the atomic auroras fade and those left on Earth find themselves struggling against more than just fallout and other survivors, the lucky ones who got away fear they made a one-way trip. Centuries later in the now-sprawling Martian metropolis, a transformed species tries to cope with life on an alien world starved of flora and fauna. Their ancestors’ actions and the distant neon blue flicker of the rewilded Earth haunt those confined to the rusty red planet. None feel it more than John’s daughter, the eminent Gloria Rook. Her mind and body are sharper than ever, but no cybernetic implant or designer chemical can dull the longing. An impossible signal hints there may be a way to return to Earth and reveals another more nefarious secret. It might just be Gloria and the Martians’ chance to finally go home, or destroy everything they’ve built.
