Amber Kivinen is moving to Mars. Or at least, she will be if she wins a chance to join MarsNow. She and twenty-three reality TV contestants from around the world—including a hunky Israeli soldier, an endearing fellow Canadian, and an assortment of science nerds and wannabe influencers—are competing for two seats on the first human-led mission to Mars, sponsored by billionaire Geoff Task. Meanwhile Kevin, Amber's boyfriend of fourteen years, was content going nowhere until Amber left him—and their hydroponic weed business—behind. As he tends to the plants growing in their absurdly overpriced Vancouver basement apartment, Kevin tunes in to find out why the love of his life is so determined to leave the planet with somebody else.

An audaciously original debut from an "immensely talented writer" (Emily St. John Mandel), Girlfriend on Mars is at once a satirical indictment of our pursuit of fame and wealth amidst environmental crisis, and an exploration of humanity's deepest longing, greatest quest, and most enduring cliché: love.
