Delany was employed by the Royal Bank of Canada as a computer programmer and systems analyst until retiring in 2007. She now lives in Prince Edward County, Ontario. She is the mother of three daughters (Caroline, Julia and Alex).

Delany is the author of the Constable Molly Smith mystery series, set in the fictional British Columbia town of Trafalgar (a thinly disguised Nelson, BC), and the Klondike Mystery series, set in Dawson City, Yukon during the Gold Rush of 1898. She is also the author of three novels of psychological suspense, set in Northern Ontario.

Scare the Light Away was the subject of a mixed review by Kirkus Reviews, which praised Delany's ability to create a tense atmosphere but felt that the mystery elements of the story were not as effective.

In the Shadow of the Glacier was described as "an intriguing series opener" by Publishers Weekly, which noted that Delany positioned the narrative well to continue into future works.

Valley of the Lost drew both praise and criticism from Kirkus Reviews, which described the novel's protagonists as "interesting" and the first three-quarters of the novel as "ingratiating", but then cited "exceptionally silly plotting" that sabotaged the book's ending.

Gold Digger received positive reviews from several publications. Writing for The Globe and Mail, Margaret Cannon noted a few anachronistic touches, but praised the novel's "great setting" and described it as "a lot of fun". In a review published in The Hamilton Spectator, Don Graves lauded the novel as "a captivating tale with lots of colour, ably researched detail and crisp dialogue that moves the story along, spinning into a satisfying, yet surprising, conclusion."

Winter of Secrets was criticized harshly by Kirkus Reviews, which described the novel as "a misstep" and blamed "lumpy prose and [a] none-too-serviceable plot".
