Web Application Hacker's Handbook deserves a special mention, as I'd used it as a reference but never gave it the attention it deserves. Although it's a bit older, it's still a solid introduction to web application testing, and does a good job of balancing breath and depth. Especially recommended for developers looking to learn more about webapp security and methodologies.
