Max has accidentally smashed an heirloom vase: the only treasure her great-great-great-great-great-great-grandma managed to save when her houseboat sank 234 years ago. Max can come clean--or, she can build a time machine! If she travels to the past and smashes the vase then, there will be nothing for her to break in the future. . . .

In spite of the warning, Max tosses a Frisbee for Boomer, directly in the direction of the vase, and their wild adventure begins again, and again, and again..."--Provided by publisher.
