I think she means the Free Guide to Linux offered for registering here. I dimly recall seeing it advertised on the front page.
Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I remember looking at it and deciding I wasn't interested.
Xstitcher, you can find a load of wonderful free guides at The Linux Documentation Project

About dot com also has some very nice Linux tutorials
I am going to ask a Mod whether this should be moved to the LQ Suggestions and Feedback Forum.
