Although an old-chestnut (first published in 1975!), this I feel is the definitive book on the project management of software engineering, and it seems to balance just the rightamount of hard-nosed, realistic, accurate, timely information and advice with dry humour and wit, to give you that "I've been there" feeling. Easy to keep handy on the shelf to dip in to when you need to restore normality and keep sane...
