D. E. Stevenson invented three main geographical areas for her characters to inhabit. These are Ryddelton, Wandlebury and the area around Mureth and Drumburly.

Miss Buncle spills into The Four Graces as well as Spring Magic. Celia's House inspired Listening Valley, where Celia makes a re-appearance. We hear of her again during Anna and Her Daughters. Anna pops up briefly in the Katherine books which link with Charlotte Fairlie (Mr. Heath the vicar makes a re-appearance this time). Later Sarah Morris ends up in Ryddelton in Sarah's Cottage to be befriended by Debbie (who made her debut in Celia's House) and to hear about Tonia (Listening Valley) and Charlotte Fairlie.

More links exist from the Katherine books, via Mr Sandford the lawyer, to House on the Cliff which links via Miss Martineau the landlady to The Blue Sapphire. The Katherine books also tell us more about MacAslan who we first meet in Smouldering Fire. Stevenson's last book, The House of the Deer (a reworking of a serial published in The Glasgow Bulletin in 1936) revisits the MacAslan family in the second generation.

Gerald and Elizabeth enter into the saga around Drumburly and re-introduce Freda from Five Windows. Jock from the Music in the Hills trilogy also knows of Freda. Bel Lamington links into these books. Bel's friend Margaret was a Musgrave and there are links from The Musgraves to The Tall Stranger which was a sequel (of sorts) to Five Windows. The Musgraves give a tenuous link back to Ryddelton via the Mulberry Coach, a story written by one of Anna's daughters and nearly performed by Delia Musgrave.

The Amberwell books link closely to Still Glides the Stream which in turn ties in with the Sarah books, in that Will and Sarah both visit Nivennes and meet with the Delormes family, although their visits are many years apart.

Books Within Books:Another recurring character is the author Janetta Walters, whose light romantic novels are either loved or loathed by Stevenson characters. We first hear of her books in Mrs. Tim Carries On and Spring Magic. She appears in person in The Two Mrs. Abbotts and The Four Graces.
