Query: An absolutely MUST READ

This book was recommended to me by the finest manager I've ever had the pleasure of working for. After reading it, I realized what set him apart was that he applied the principals described by DeMarco and Lister and what a difference it made! After reading it, I bought two more copies, one for my current boss and one for another developer. Both were heard singing its praises to their bosses. The book is good enough that it they either bought it for their bosses or handed their own copy to them. You can't get a much better recommendation than that.
