As always, Mercy is a blue ribbon winner. The characters are hilarious, partly because they are so true to life. Illustrator Chris Van Dusen's pictures add to the story (Francine Poulet's license plate reads "CLUCK"; Mercy's bowl of lemonade is garnished with a slice of lemon). Young fans no doubt already find themselves craving a new Mercy story in much the same way that the porcine wonder pines for hot crunchy toast dripping with butter.

Mercy Watson fans will surely love this deliciously, ridiculously funny story...Chris Van Dusen has produced delightful illustrations that perfectly compliment Kate DiCamillo's prose.

Funny, giggly, and silly...hilarious, bold, brightly colored illustrations that almost glow.
