Simon A. Forward is an author and dramatist most famous for his work on a variety of Doctor Who spin-offs. He currently lives and works in Penzance with his wife as a full-time writer. Forward specialises in sci-fi novels such as Doctor Who. His most recent work is Evil Unlimited for the Kindle. Simon's first published work was the short story One Bad Apple in BBC Books' Doctor Who anthology More Short Trips (BBC Books, 1999). Following this, Simon had a proposal for a Past Doctor Adventure accepted, and the subsequent novel, Drift, was published by BBC Books in 2002. Having a successful novel behind him, Simon contacted Gary Russell about the possibility of writing for Big Finish's range of audio adventures. The enquiry resulted in him writing the audio play The Sandman (Big Finish, 2002). Simon went on from this to write several short stories for the Big Finish Short Trips volumes, as well two subsequent audio adventures. Forward also wrote the novella Shell Shock (Telos Publishing Ltd., 2003). This was part of their range of Doctor Who novellas and is now out of print. In the same year, Simon also had another Doctor Who novel published by BBC Books, the Eighth Doctor Adventure Emotional Chemistry (BBC Books, 2003). 2009 saw two novelisations of the BBC television series Merlin, followed by a third in 2010. 2010 also saw the independent publication of an original SF Comedy, Evil UnLtd, in ebook form.

Jacqueline Rayner is a best selling British author, best known for her work with the licensed fiction based on the long-running British science fiction television series Doctor Who. Her first professional writing credit came when she adapted Paul Cornell's Virgin New Adventure novel Oh No It Isn't! for the audio format, the first release by Big Finish. (The novel featured the character of Bernice Summerfield and was part of a spin-off series from Doctor Who.) She went on to do five of the six Bernice Summerfield audio adaptations and further work for Big Finish before going to work for BBC Books on their Doctor Who lines. Her first novels came in 2001, with the Eighth Doctor Adventures novel EarthWorld for BBC Books and the Bernice Summerfield novel The Squire's Crystal for Big Finish. Rayner has written several other Doctor Who spin-offs and was also for a period the executive producer for the BBC on the Big Finish range of Doctor Who audio dramas. She has also contributed to the audio range as a writer. In all, her Doctor Who and related work (Bernice Summerfield stories), consists of five novels, a number of short stories and four original audio plays. Rayner has edited several anthologies of Doctor Who short stories, mainly for Big Finish, and done work for Doctor Who Magazine. Beyond Doctor Who, her work includes the children's television tie-in book Horses Like Blaze. With the start of the new television series of Doctor Who in 2005 and a shift in the BBC's Doctor Who related book output, Rayner has become, along with Justin Richards and Stephen Cole, one of the regular authors of the BBC's New Series Adventures. She has also abridged several of the books to be made into audiobooks. She was also a member of Doctor Who Magazine's original Time Team.
