The glamorous headline-grabbing Lyric Charlton has finally put her unhappy past behind her. She has her adoring family and a lover who worships her, but as Lyric has always known, life is a very uneven path, and things have a habit of tripping you up when you least expect it. When tragedy strikes at the heart of her family, Lyric's world is once again thrown into turmoil. Before her very eyes everything she thought was safe now seems more fragile than ever. From the luxurious yachts on the Mediterranean to the super-charged atmosphere of the Melbourne Cup. From the brilliant white ski slopes of Klosters to the serenity of a Buddhist retreat, Infidelity is a tale of lovers and losers, cheaters and winners, as only Tara Palmer-Tomkinson can tell it.
