Who is Lily Murphy? She has platinum-blonde hair but dark eyes; she was born in New York to the daughter of a ballet dancer, but educated in England, and now she is a restaurant critic in Dublin. In Sustenance, we journey into Lily's world of sumptuous meals, but also into her troubled past, where the dinner table was heavy with menace. And we meet Nicholas Savage, the brilliant chef with whom she falls in love, but who, like Lily, harbours a dark secret.
