Tony Littlejohns was born in north London in the 1960s, the youngest of three siblings. He worked in engineering for twenty-one years after leaving school, but left after his divorce in 2001 to pursue other endeavours. From his voluntary work with Raleigh International between 2001 and 2006 he developed an interest in survival and bushcraft, having spent months living in the jungle while working on projects in Belize, and later work in Chile.
After fourteen rather itinerant years moving around the UK for a variety of jobs, he settled in Bexhill-on-Sea, East Sussex, in 2015, where he now lives, and is retired. His main interests are photography, walking, reading and writing. He has had a love of writing and poetry for thirty years and always dreamed of one day writing a book. The Hoffmann Plague was his first novel, published in 2018, with Sisters and Quest following in subsequent years to complete the post-apocalyptic trilogy set in and around Bexhill. A collection of short stories related to the trilogy followed in 2025.
