Jenny Colgan

J. T. Colgan (born 14 September 1972) was the pen name used by Jenny Colgan when attributed for the writing of the Eleventh Doctor novel, Dark Horizons. She otherwise mainly wrote under "Jenny Colgan", and was credited as Jenny Colgan for her second DWU work, the Eleventh Doctor Time Trips short story Into the Nowhere.

She once claimed that her entirely fictitious middle initial stood for "Tardis". A Scot by birth, she may be the only person to have written a Doctor Who novel whilst living in France. , a reasonable amount of her work contained Scottish themes or locales, and Dark Horizons was no exception.

Her novel-writing career started in earnest at the dawn of the 21st century, when she began releasing, on average, a little over a book a year. Though typically a writer of romantic comedies for young adults, she was thrilled to be asked to write a Doctor Who novel, as she was a lifelong fan. Her association with Doctor Who began as a child watching Tom Baker and voraciously reading Target novelisations, but her fandom waned during the Colin Baker and Sylvester McCoy tenures — only to be rekindled by the Russell T Davies and Steven Moffat eras.
