Tanya Sue Huff (born 1957) is a Canadian fantasy author. Her stories have been published since the late 1980s, including five fantasy series and one science fiction series. One of these, her Blood Books series, featuring detective Vicki Nelson, was adapted for television under the title Blood Ties.
Born in Halifax, Nova Scotia, Huff was raised in Kingston, Ontario. Her first sale as a writer was to The Picton Gazette when she was ten. They paid $10 for two of her poems. Huff joined the Canadian Naval Reserve in 1975 as a cook, ending her service in 1979. In 1982 she received a Bachelor of Applied Arts degree in Radio and Television Arts from Ryerson Polytechnical Institute in Toronto, Ontario; she was in the same class as noted science-fiction writer Robert J. Sawyer; they collaborated on their final TV Studio Lab assignment, a short science-fiction show.
In the early 1980s she worked at Mr. Gameways Ark, a game store in Downtown Toronto. From 1984 to 1992 she worked at Bakka, North America's oldest surviving science fiction book store, in Toronto. During this time she wrote seven novels and nine short stories, many of which were subsequently published. Her first professional sale was to George Scithers, the editor of Amazing Stories in 1985, who bought her short story "Third Time Lucky". She was a member of the Bunch of Seven writing group. In 1992, after living for 13 years in downtown Toronto, she moved with her four large cats to rural Ontario, where she currently resides with her wife, fellow fantasy writer Fiona Patton. Her current pet population consists of six cats and what she describes as an "unintentional chihuahua".
Huff is one of the most prominent Canadian authors in the category of contemporary fantasy, a subgenre pioneered by Charles de Lint. Many of the scenes in her stories are near places where she has lived or frequented in Toronto, Kingston, and elsewhere. This author frequently uses character names as the names of people in her circle of acquaintances. A prolific author, "she has written everything from horror to romantic fantasy to contemporary fantasy to humour to space opera."She appeared in a 2009 documentary Pretty Bloody: The Women of Horror.
