Sunny Smith is running from her memories. It's what she does. Settling in a beautiful but remote area of Cornwall she thinks she has found the perfect place to help heal the emotional wounds left by her husband's untimely death. She believes she has found a sort of freedom but her peace of mind becomes threatened by Jimmy Fisher. Jimmy is an artist. He is also a serial seducer. Although she has been warned about his past, Sunny finds she needs what he offers. Jimmy, too, is unable to remain as detached as he usually prefers to be and unwittingly leads Sunny towards savage violence and an overwhelming guilt. A guilt that demands the ultimate expression of remorse. The Catalyst is a story of a passionate love affair that endures despite everything ... although not quite as you might expect.
