Adult colouring books have been topping headlines as the latest craze in book publishing, but should we be surprised?
The current bestselling title at Amazon is Secret Garden, an Adult Colouring Book (no...not that kind of adult!). Illustrated by Johanna Basford, it is a beautiful compilation of pen-and-ink illustrations just begging to be coloured in. It even doubles as a treasure hunt, with hidden tiny creatures and even blank spaces to continue drawing!
