Taken from the back of the book:
'The mosses live in a strange world, a kind of fairytale world, hence the title of this book. (Mosses) cover very deep problems from early childhood trauma's, mental handicap, schizophrenia and the like. They are needed for people who are unable to cope with life, to find a job and an income, to live on their own.'
This book is the result of a mass proving of mosses, with all of the information gathered, together with the botany of the mosses and their classification. It is a huge extension of the previous available information on mosses and although described as tentative by the author, he also states 'it is better to have a start than to have nothing.'
