I wouldn't say this is a book for anyone - certainly not 'self-styled no-hopers'. You have to have some basic idea of how to draw, of materials and techniques, but where it does excel is as a source of inspiration.
The book is divided into chapters which cover line and mark making, tone, composition, observation and so on. Each chapter contains exercises and, most usefully, examples and further reading/looking at artists who have captured that skill.
I find it a beautiful thing to leaf through as well as a source of inspiration.
