I've been a fan of Hornby's novels for years, long before his work attracted new readers who saw the film adaptations of HIGH FIDELITY, ABOUT A BOY and FEVER PITCH.
HOW TO BE GOOD examines the breakdown of a marriage that seems completely stable from the outside. Kate is a successful MD with a thriving practice and her husband David is a freelance writer known for his irascible columns in the local paper. The story is told from Kate's perspective and explores how she struggles with the notion of goodness. She is the one who compromises the marriage by having an affair, and then watches as her husband follows his own path of self-destruction on his intended road to enlightenment with a different kind of interloper metaphorically sharing their marriage bed.
Hornby writes convincing characters, plausible plots and authentic dialogue that will have you believing every word of it.
