This is one of the best novels I've read in a long time. It's written in alphabetical glossary entries (A Ambition, Ants, Attitude, etc.) and tells the story of Verity Bell, a British woman in her 20's, working in the media, who gets romantically involved with a married man. Although it's being marketed as chick lit, it's far more witty and substantial than the other books out there geared at women, and I think men could enjoy it, too. The novel is observational about little things in everyday life, literary and damn funny, too. The format makes for a clever, atypical storytelling technique. I finished it in two days and when I got to Z, I wanted to go right back to A and start again. I could go on and on about how much I love it.
If you haven't read this book, I can't recommend it highly enough, and if you have I'd love to hear your thoughts.
