When she's not moodily denying the existence of extraterrestrial life in The X-Files or racking up Olivier nominations for her theatre work, Gillian Anderson is sitting in her attic writing novels, the first of which - A Vision Of Fire - dropped in 2014. A sci-fi thriller based on the life of single parent Caithlyn O'Hara, whose humdrum existence is shattered by violent dreams of a world-ending catastrophe, the book performed well enough for Anderson to pen a second installment, A Dream Of Ice, a year later, in which the put-upon protagonist develops healing powers. As you do. Anderson has promised further books as she works her way through the elements - fire, ice, water, air - delighting fans of The X-Files who are finding much to love in the dense, well-researched narratives and relatable characters.
