In 2073, controversial agronomist Dr. Alex Cole has dedicated her life to mutagenetic food, the only solution to feeding a world torn apart by climate change. When fierce opposition from radical environmentalists wipes out her lab funding, a surprising lifeline appears in the form of Mansoor Al Kaabi, a charismatic Emirati businessman who needs a sustainable food supply for his guests on the Moon's first hotel.

Alex moves to the Moon colony with Mansoor, and they immediately dive into the challenging work. As she smuggles in illegal chickens, fights a vexing tomato fungus, and dreams of olive groves on the Moon, Alex is surprised to find herself falling in love not just with the lunar colony, but with Mansoor, whose vision for the future of the Moon extends far beyond luxury hotels.

Back on Earth, eccentric genius Victor Beard and Mansoor's younger brother Rashid fight to push the Homestead Act through Congress. Without the support of the US government, they'll never be able to achieve their goal to relocate humanity to the Moon and secure a second chance for life on Earth.

When eco-terrorists threaten the lunar colony, Alex, Mansoor, Victor, and Rashid must choose what they're willing to die for-and what they're really living for. Is it their grandiose visions of saving the planet-or is it each other?
