How cool is 36-year-old Will Lightman? Sub-zero, according to the questionnaire in his favorite men's magazine. Not only does he own more than five hip-hop albums (five points), he's also slept with a woman he didn't know very well within the last three months (another five points). Targeting single mothers, he joins a single parents' group under false pretenses and is soon drawn into the lives of depressed Fiona and her bright 12-year-old son, Marcus. Suddenly, his life is messy and complicated, and he's horrified when he realizes that he's now hanging with the type of people who gather around the piano to sincerely sing songs like "Both Sides Now" with their eyes closed. This is Hornby's second novel (following High Fidelity, 1995), and it's obvious he has an uncanny ability for homing in on wholly contemporary, often serious topics and serving them up in truly hilarious fashion. His skillful analysis of hipster angst has obviously struck a chord--this novel has been sold to filmmakers for more than $3 million.
