Kathy hated always having to baby-sit her little sister Megan. Why couldn't her brother Duke help sometimes? And Megan had begun talking about her imaginary friend Natalie again too. Was it Kathy's fault for being so mean to her?

Just when Kathy was sure things couldn't get worse, something much worse happened. While they were at the park Megan disappeared! Kathy had only taken her eyes off her for a couple of minutes.

Fortunately the Best Friends were there to help Kathy with her search. But what they were about to discover and the experiences they were about to have would truly amaze them all.

The third book in the Best Friends series, Kathy's Baby-sitting Hassle is an intriguing tale of mystery and danger. A story that will entertain 9- to 12-year-olds and give them a new understanding of friendship and courage.
