Watson was born in
Seattle, Washington and attended
Reed College. She began writing fiction in 1953; while doing so she worked for Great Books and co-wrote the audio-visual reading course,
Listen and Learn with Phonics. In 1964 she moved to England, where she lived for 24 years, writing meticulously researched juvenile historical fiction featuring feisty and adventurous heroines, such as
Jade, published by
Henry Holt and Company. Her other activities included
Scottish highland dance, teaching
Judo, in which she earned a black belt, and
Mensa International. The publishing climate for juvenile fiction eventually changed, and by the mid-1970s her books had gone out of print. Watson eventually returned to the United States, taking up residence in
Santa Rosa, California, where she became active in
feral cat rescue organizations. All the while her fans were pleading for her books to be republished; eventually Image Cascade reprinted many of the novels. Sally has continued to add to her English family tree series and has also published several young adult novels set in
Ancient Egypt. Her most recent books are
Tailwavers, a story for all cat lovers, told in part through a series of letters,
The Next Pharaoh, a novel continuing her Egyptian history,
Return of the Exiles, set during the rebirth of Israel, and
Dance to a Different Piper, a memoir covering the first 30 years of her long and productive life. Watson died on March 11, 2022, in her hometown of Santa Rosa, California, at the age of 98. == Bibliography ==
