I think these are the only two picture books I read off the Cybils list. (I've read myself into a mild coma, so I can't be sure.) They are both particularly engaging.
I read Gaston by Kelly DiPucchio with illustrations by Christian Robinson first and was delighted. Gaston does not exactly fit with his teapot poodle siblings, Fi-Fi, Foo-Foo, and Ooh-La-La. Does his mother care? Not a bit.
One day this family is out at the park where they meet another family of dogs with a member, Antoinette, who doesn't fit in with her siblings, Rocky, Ricky, and Bruno. Quelle horreur! Has a terrible mistake been made?
Gaston is all about feeling right as well as looking right. It's amusing and quick and kind of deep. I did wonder if some kids reading this will learn about the possibility of being switched at birth and be a little shaken. But, hey, literature is dangerous.
Flora and the Penguin by Molly Idle is one of those books in which the pictures tell the tale. There are no words. I can't recall when I've seen a book in which facial expressions and body language--even on the part of the penguin--did such a terrific job of conveying emotion and action.
Gaston and Flora and the Penguin are both Cybils nominees in the fiction picture book category.
