Tobias Schlitt mentioned today that the book from him and fellow coauthor Kore Nordmann, a guide to the eZ Components framework, has been made the featured book of the month over on DynamicWebPages.de.
On the website you now find a picture of the book in a very prominent place and an extensive recension (German) linked from there.
You can find out more about the book and pick up your own copy from Amazon.
