The Travelling Hornplayer: Brother, Book 3 (Unabridged‪)‬

Lydia is killed in a car accident, but she returns to her bereft sister as a benign ghost who, nonetheless, comes to haunt the lives of those around her in unexpected ways: Jonathan Goldman, whose flat Lydia is running from when she is knocked down; his daughter, Stella, who has discovered that her father has been having an affair with the gladiatorial Sonia; Stella's genius painter-boy lover, Izzy, whom she leaves behind as she flees to the arms of kindly Peregrine. Along with good stepmothers, bad mothers, strange professors and wicked monks, their lives collide in a breathtaking finale.
