Just think about it for two seconds and give a very simple description, be nice and don't get elaborate. If they're interested, politely give more detail if they want. I've been reading Habermas at work breaks for several months and the answer "it's a sociology book, it's about how people communicate with each other" is a truthful, non-condescending, and appropriate speech act in the circumstances, stuff he deals with in the book itself.
