I just added two new books in my bookshelf: Refactoring Databases: Evolutionary Database Design and The Mythical Man Month and Other Essays on Software Engineering.

I am currently reading the latter. There are very valid reasons for this book to be a classic. It provides a great description on how real-world project management works, and which are the important steps and strategies to cope with well known mistakes and issues during development of large systems. It is very broad, never too specific, but it is full of insights. A mind-opening book I strongly suggest.
