This is a Horrible Colouring Book - Terry Deary

History can be horrible - especially when you get into the grisly
details. And this colouring book is no different. There will be
no need for 'buttercup yellows' or 'sky blues' in this book. More
like 'blood-stained browns' or 'revolting reds'.
From the rotten rituals of the Egyptians to the cruel crimes of Blackbeard,
this colouring book is a terrible trip through history,
with all the gore and more. Packed full of pirates to paint, Colloseums
to colour and evil Incas to illustrate, this is a colouring
book - but not as you know it.
