Many of the 52 stories in Sterling's anthology Grimm's Fairy Tales concern royal families – Kings, Queens, Princes and Princesses – so a castle seemed a great way to take young readers into this world. At the same time, it's not specific to any one story in the collection.

The twist is that the little princess reading Grimm's Fairy Tales in the foreground is not a character – she's a real kid. The idea is that she has created the castle in her imagination. This drawing was featured as a full-page reproduction in Communication Arts' 50th Illustration Annual in 2009.

The black and white drawing is for "Rumplestiltskin".
