Karen's Roller Skates (Baby-sitters Little Sister #2)

Karen will try anything!

Karen has new roller skates. She is a very good skater. She can ever do tricks.

But oh, no! Karen falls down and breaks her wrist! She has to go to the hospital and get a cast.

Karen wants somebody famous to sign her cast. It isn't going to be easy-but Karen won't give up till she gets the job done!
