Leading Geeks: How to Manage and Lead the People Who Deliver Technology is a book written by Paul Glen.  This book was given to me by one of my previous employers.  The central idea of the book is that traditional management practices may not be very effective when it comes down to managing technical teams.  I found the book to be very easy to read and I think there are some great tips on how to manage and lead technical teams.  What is rather interesting that even if you are a technical person who is promoted into a management role, you tend to adopt traditional management styles than the ones you would have prefered as a techie yourself.  This book discusses how techies think, what to expect and what not to expect from them.  If you are leading a technical team or you are preparing to become a technology leader then this book is definitely for you.  The books is available online.
