It's written by Joachim Klang and Oliver Albrecht who, according to the introduction, are active members of the German AFOL scene and 1000Steine.
It's divided into two sections. The first provides instructions and inspiration for building a micro-scale LEGO city like that shown on the cover. Most of the 30 instructions are for vehicles of some sort although some small buildings and trees are also included. The second, much smaller section, has instructions for five minifig scale 'professional models', four cars and a helicopter.
This page, showing the last page of one set of instructions, and the first of another show how it's laid out: A nice photo of the finished model, shown in the context of the micro-scale city followed by several pages of instructions that end with a parts list.
The models use a lot of advanced building techniques that you might not find in official models, so from that point of view, it's educational, and in fact there are a few pages showing such techniques at the front of the book, some of which I've never come across (like using lever handles jammed into the bottom of plates to join them bottom-to-bottom).
If you're looking for building inspiration, I highly recommend this book: there are many models in it that make you think "'wow, that's cool!" and which are likely to have you reaching for your parts drawers to build them yourself. My only criticism is that the writing on the spine is the wrong way up: the text should start at the top and end at the bottom: why do some publishers think otherwise?!
