The actress is returning to the genre that made her famous thanks to publishers at Simon & Schuster, who have a new imprint dedicated to speculative fiction called Simon451.
Along with co-writer Jeff Rovin, Anderson will write and develop a new franchise, titled the EarthEnd Saga. The first book, A Vision of Fire, follows the fortunes of a child psychiatrist who specialises in treating kids who have suffered trauma from natural disasters and war, and meets a girl with unique troubles in the process.
Anderson is looking forward to the new venture, claiming her time on The X-Files has given her the perfect background material.
She tells Entertainment Weekly, "It’s been a fantastic experience. I enjoy writing, but don't usually allow myself the time, and I don't think I'd ever think to write something in this genre without the prodding of someone like Jeff.
"After nine years of living in a semi-science-fictional universe, I think I now have an ingrained knowledge and rhythm for it."
A Vision of Fire will be released in October (14).
