Sales of colouring books skyrocketed this year, as grown-ups turned to the childhood past-time to combat stress and anxiety.

But Bigwood's creation is a brilliant way to vent frustrations and anger on those particularly horrific days when pretty patterns won't cut it. After all, swearing has been proven to be a sign of intelligence.

You can download the book for £13 on Etsy right now or order an advanced printed copy for £10.75. Unfortunately, it won't get to you in time for Christmas; Bigwood anticipates a delivery after 10 February.

In the meantime, take a look at a few pages from the book below.
