[1] Although one Shell Seekers character, Noel Keeling, is a significant figure, a new cast is introduced.

The characters of the book all have a problem to overcome, such as jealousy, envy, or greed.

Lottie Carstairs, released from the local psychiatric hospital drives Violet's friend (and employee) Edie to distraction - along with everyone else, disagreement over their son's schooling drives parents Edmund and Virginia Aird ever further apart, the Balmerinos are deeply troubled by debt, and into all this, the bewitching and beautiful Pandora Blair, who ran away from home twenty years before, adds her own brand of chaos.

September was made into a mini-series film in 1996, and starred Edward Fox, Michael York, Mariel Hemingway, and Jacqueline Bisset, Jenny Agutter (as Isobel Balmerino), Judy Parfitt (as Verena Steynton).

September was also released as an audio book, and, like The Shell Seekers and Coming Home, it was read by Lynn Redgrave.
