What Karla Wants

This book was previously titled "Friends of Choice."

Karla needs permission to stay overnight at Carol's because it is the only way she can go to the party her new friends have invited her to. She needs to give Carol an answer before they cancel the invite. But Karla is afraid her mother will say no. Mrs. Centon says no to a lot of things Karla wants to do for apparently no reason at all. How can she convince her mother to say yes despite knowing she will say no?
