Not a developer book . I will have to put myself in the same corner as a few of my fellow reviewers, this is not a developer book, by far. It also has a lot of repetition in it. You can explain the different security groups twice, but 5 times seems like a little too much... The fact that web parts and customisations are not covered is like the biggest dissapointment to me, because that is what I am looking for in a book. How to use Sharepoint is something you can learn in the online help
Output:
NEG
