When Lucy Brennan, a Miami Beach personal-fitness trainer, disarms an apparently crazed gunman, the police and the breaking-news cameras are not far behind. Within hours, Lucy becomes a hero. The solitary eye-witness, the depressed and overweight Lena Sorenson, thrilled by Lucy's heroism and decisiveness, becomes obsessed with the trainer and enrolls as a client at her Bodysculpt gym. It quickly becomes clear that Lena is more interested in Lucy's body than her own, and a budding fatal attraction takes hold. However, it's when Lucy imprisons Lena, and can't stop thinking about the sex lives of Siamese twins, that the real problems start. In Lucy and Lena, Irvine Welsh has created two of his most memorable female protagonists, and one of the most bizarre, sadomasochistic folie à deux in contemporary fiction. The Sex Lives of Siamese Twins taps into two great obsessions of our time--how we look and where we live--and tells a story so subversive and dark it blacks out the Florida sun.
