Hey,
          
          I am looking for this book.
          It was about a student in college( a girl) and she had this crush on her teacher (I think the subject was archeology or geopraphy) that's the reason she dropped out of the class.
          At a family party she hit on him, and he rejected her.
          So her best friend was still in that class, and that class was going on a dig somewhere. But her best friend would only go if she went.  So the father of her best friend pulled some strings so she would be able to come along. 
          I remember that on the dig she was very excluded and had to go places with a bike, and that she became friends with the people at the hotel and stuff.
          
          And of course you had the sort of romance between this teacher and her.
          
          Anyone know the title?
