The Art of Project Management (Theory in Practice (O'Reilly))
"The book is written in an easy and witty style that makes for an enjoyable cover-to-cover read, although the structure of the book makes it easy to refer to particular sections as required.  Whether you are an experienced project manager or making the transition from developer to manager, I thoroughly recommend that you read "The Art of Projects Management" and keep a copy with you at all the times!" - Jenny Smith, The Developers Magazine - Jan/Feb 2007
