Ruth Glick, née Burtnick (born 1942) is a best-selling US writer of healthy cookbooks, romance and young adult novels. She has written dozens of novels under the pseudonym Rebecca York; until 1998 these were written in collaboration with Eileen Buckholtz.
Ruth Burtnick was raised in Washington, DC, the daughter of Lester Burtnick, a psychiatrist, and Beverly Miller Burtnick, a middle-school science teacher. She earned a B.A. in American Thought and Civilization from George Washington University and an M.A. in American Studies from the University of Maryland. In 1963, she married Norman Glick. They have two children: Elissa, a librarian, and Ethan, a Foreign Service Officer.
After several years as a stay-at-home mother, Glick decided to pursue a career. She enrolled in a course at a local community college to help her choose a career. The class helped her identify a talent for writing. For the next few years, Glick wrote articles for local newspapers, and sold several articles on a freelance basis to The Washington Post and the Baltimore Sun.
When Glick wrote her first novel, a children's science-fiction story, it was rejected by five different publishers. The last, Scholastic, sent a two-page note detailing the flaws in the manuscript. Glick rewrote the story based on those suggestions, and Scholastic later purchased the book. It was released in 1982 as Invasion of the Blue Lights. The same year, Glick partnered with a friend, Eileen Buckholz, to write romance novels. Using the pseudonym Rebecca York, the duo wrote over 40 novels and novellas together. Most of these were romantic suspense.
In the late 1990s, Glick decided that she no longer wished to work in collaboration, explaining that "sharing my vision with someone else stopped being satisfying for me". She and Buckholz agreed that each could release solo novels under the pseudonym, provided that the cover page also listed their real names. In 1998, Glick's first solo novel as Rebecca York was published as Nowhere Man.
According to Glick, as of 1999 over 5 million copies of her books were in print in 17 languages.
Many of her novels are published under the Harlequin Intrigue line, and in June 2003, she became one of the first authors published under Berkley's new Sensation imprint.
Glick also is the author of cookbooks focusing on healthy eating, some of them with Nancy Baggett. She sometimes hires trained chefs to test the recipes that she creates, and makes sure that every recipe is tested at least three times before it appears in one of her cookbooks.
Glick is the head of the Columbia Writers Workshop.
