I would recommend you three IT Security Books:
Web Application Security: A Beginner’s Guide
Security Metrics: A Beginner’s Guide
Securing the Clicks: Network Security in the Age of Social Media
They have been published in recent months. They are timely, useful and valuable. You can find out more on http://pentestmag.com/ in section "Reviews".
All three books are easy available through PenTest Magazine. Just buy annual subscription and choose the best for you!
