Baby-Sitters Little Sister #3 Karen’s Worst Day. Katy Farina. 2021.

Karen is having a terrible day. Her new jeans are missing, there's no prize in the Crunch-O's box, and Boo-Boo the cat won't play with her.

She even gets punished and sent to her room!

Karen tries everything to make her day better, but nothing is going right, and her bad luck just won't go away. Will this be the worst day ever?
