Emma and her grandpa, Pop, are tap-dancing pals. They dig-shuffle-chug through town and put on a c lickity-clacking, tip-tapping show every year on Emma€s birthday. But Pop is getting old. He starts forgetting things, even Emma€s birthday. And he stops dancing. Can Emma help Pop€s feet remember how to dance? Clickity-clack, clickity-clack, stomp-stomp-clickity-clack. . . . Endearing illustrations rendered in gouache and pencils show that even the smallest act may spark a memory in an Alzheimer€s sufferer.
