Readers interested in how words and pictures work together in cartooning to tell a story or convey information will find plenty to enlighten them here. The lesson is delivered in the context of a story about a knight in search of a missing princess. The plot is slight, but the silliness is delightful, from the metaphorically knock-kneed steed named Edward to the educational elf who explains to the knight how cartoons work as the adventure progresses. One unexpected twist and turn follows another in a volume that concludes with a simple drawing lesson. (Ages 7–10)
