Query: Great book.... no fluff, pure gold information....

If you have read some other PR books you know they are 80% fluff and 20% content.... well, this one is 100% content and an easy read. Before you know it you'll be giving it a second read to make sure you didn't miss any of the juicy tactics provided. I bought it using a coupon from UnderTag.com, so it was almost free for me.
