I should point out that although this ebook can be loaded onto a normal kindle e-reader it will not be that good; to view this properly you will need a tablet device, especially as you can zoom into pictures and text then, which you can't do with a standard kindle e-reader. There are a few pictures that are slightly erotic, but a lot aren't, and have battles and such like taking place, so although this isn't ideal for little ones, older teens will be okay with this.
There is an active table of contents as such, but this will only take you to sections, so I am afraid, if you have a favourite picture that you want to come back to again, then it is best to bookmark it. This is interesting because as well as the finished artwork you have the original sketches, and then the process from one to the other. This is an interesting and artistically pleasing book, that should hopefully give you quite some pleasure, and not only do you have the artwork, but also text explaining about the pictures and the process for realising them to the full.
