Baby-Sitters Little Sister by Katy Farina " Karen`s Roller Skates"

It`s going to be a great weekend! Karen has new roller skaters and is a very good skater. She is looking forward to trying same new tricks. But, oh no! Karen falls down and has to go to the hospital! Her wrist is broken!
Karen is determined to get everyone she knows - plus someone famous - to sign her cast. It is not going to be easy, but she won`t give up until the job is done.
