The top two bestselling books on Amazon right now are Johanna Basford's The Secret Garden and Enchanted Forest, both coloring books for adults.
"I think it is really relaxing, to do something analogue, to unplug," Basford told The Guardian. "And it's creative. For many people, a blank sheet is very daunting; with a colouring book you just need to bring the colour. Also there's a bit of nostalgia there. So many people have said to me that they used to do secret colouring in when their kids were in bed. Now it is socially acceptable, it's a category of its own. These are books for adults. The art in my books is super intricate."
