Create Space has drawn a high score from a very large number of listeners, and in a category as crowded as this one that volume is the clearest evidence available that a book has been useful to people rather than merely bought by them.
Dilly Carter is filed by our catalogue at the junction of health and wellbeing and home and garden, which is precisely where the modern decluttering book lives. The premise of that shelf is that the state of a room and the state of a mind are related, and the good books in it treat the tidying as the means rather than as the point.
The author reads the book personally, which in practical writing is worth a great deal, since instructions land better in the voice of whoever devised them.
