Andi to the Rescue — Susan K. Marlow

This is so embarrassing. Andi's teacher, Miss Hall, is sick--and Mother is the substitute teacher. What will Andi's friends think?

But it turns out embarrassment is the last thing Andi needs to worry about when two outlaws kidnap Andi and her mother after school in a case of mistaken identity! They can't even tell the kidnappers a mistake has been made without putting themselves in even more danger.

Now they're being held in a remote cabin until Mother can teach the man in charge how to read--and he's willing to go to any length to make it happen. Andi must escape and find help. But can she lead a rescue party back to Mother before the outlaws take their new teacher--and disappear forever?
