Sony has bought movie rights to Alexandra Monir’s upcoming space thriller “The Final Six” in a preemptive deal.

The studio made the deal based on the book proposal with only a few chapters being available — even before a publishing deal was in place. The auction for the book’s publishing rights is imminent.

The story imagines a present-day world under a first-of-its-kind coalition between the United Nations and the international space agencies, with a plot to send a team of six intrepid teenagers to create the first human settlement on Jupiter’s moon, Europa. The book will carry themes of environmentalism, global unity and leadership.

Josh Bratman at Immersive Pictures is attached to produce. Bratman has several films in development with Sony, including Medal of Honor recipient Clinton Romesha’s memoir “Red Platoon,” which Dutton published on May 3; and Melanie Raabe’s thriller “The Trap” with producer Elizabeth Cantillon for TriStar. “Carol” screenwriter Phyllis Nagy is adapting the latter.

Lauren Abrahams will oversee “The Final Six” for the studio.

Monir is represented by Gersh and managed by Brooklyn Weaver at Energy Entertainment. Her attorney is Chad Christopher. Gersh and Energy are also representing publishing rights.
