From the back cover:
the three roommates never thought they'd spend Christmas vacation together. But during the holidays, when Andy and her family need extra waitresses in their restaurant, Jane and "Toby fly to Chicago to help. The girls quickly find out there's a lot more to waitressing than wearing uniforms and making tips, but andy and Toby get the hang of it.
But Jane isn't sure she's cut out to be a waitress. She has problems balancing trays and problems filling orders. And once she meets Zach Foster, a handsome but opinionated boy from Chicago, her life doesn't get any easier. Can Jane be a good waitress and a good friend with boy problems, too?
