Nip 'N' Tuck by Kathy Lette

Lizzie's life is pretty damn perfect, until she realises she's about to hit the dreaded 4-0. But losing her job to a younger journalist is not the only ingrown pube in the bikini wax of Lizzie's life. Her surgeon husband, Hugo, unexpectedly falls for an actress who keeps fit doing step-aerobics off her own ego. Lizzie has always believed brains to be more important than beauty, but up against a sex goddess, principles and profundity are about as useful as a eunuch at a whipped-cream orgy. Must she go under the knife to win back the man she loves? The answer is as obvious as a pre-1990 nose job.
