Say Hola, Sarah — Patricia Reilly Giff

Caramba! Sarah Cole can't believe it. Benjamin  Bean has wrecked her whole weekend. In front of the  whole class, he told Mrs. Halfpenny that Sarah  would do a report on Columbus with him. But Sarah  doesn't know one thing about Columbus. Now how can  she work on her Spanish notebook with Sarah Ortiz?  How can she have fun at the Columbus Day party at  the Library? Luckily Columbus Day brings all kinds  of surprises, including a visit from Anna's cousin  from Columbia.
