Jenny Colgan

Jenny Colgan wrote the Eleventh Doctor novel, Dark Horizons, under the pen-name J.T. Colgan and her short story, The Triple Knife, as Jenny T. Colgan. She otherwise wrote under her full name and was credited as Jenny Colgan for her later DWU works, Into the Nowhere, A Long Way Down, and All the Empty Towers.

She once claimed that her entirely fictitious middle initial stood for "Tardis".

, 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.
