They’re just harder to come by.
Ellen Raskin was a children’s author whose complex, playful novels are enormously rewarding for adults as well as kids. Sadly, she only wrote four of them – four puzzle-mysteries which I return to often, because they are always revealing new aspects, new elements. (I say sadly, but I only half mean it – we are so lucky to get those four novels.)
And Raskin was an illustrator as well as a novelist. She created over 1000 book jackets, including classics like the original cover of A Wrinkle in Time. And alongside the jackets, she created children’s picture books – large format, bold designs, a story or poem to lead you from the start to the finish.
