This illustration portrays the young princess Dinah in with a Spade (card soldier) companion as they enter an enticingly beautiful yet dangerous forest grove of giant bioluminescent mushrooms. 

Here we have Cheshire, the villianous and scheming advisor to the king, awaiting a clandestine meeting in the dark hidden passages behind castle walls.

This was the first of the series. Dinah and her deadly giant war horse Morte prepare to enter a dangerous forest called the twisted wood.
