Every day Isaac the Ice Cream Truck drives through the streets, singing his song and bringing ice cream to the people of the city. Even though he makes everyone happy, Isaac begins to doubt himself. He's not the biggest truck or the fastest truck or the strongest truck. Isaac wishes that he were special too.

This is a warmhearted story with a satisfying ending, when Isaac learns that even a small ice cream truck can make a big difference. The music and lyrics for Isaac's ice cream song are printed on the book's last page.
