I mean to do something grand. I don’t know what, yet; but when I’m grown up I shall find out.

Katy Carr is the longest girl that was ever seen. She is all legs and elbows, and angles and joints. She tears her dress every day, hates sewing, and doesn’t care a button about being called “good.” Her head is full of schemes and one day she plans to do something important. But a great deal is to happen to Katy before that time comes.
