She wants to <u>explain her reasons for writing a memoir.</u>
Explanation:
<em>A Girl named Zippy: Growing Up Small in Mooreland, Indiana</em> is a memoir of the narrator/ author Haven Kimmel. She used this book to describe the childhood life that she and her family had in the small town of Mooreland, and also as a means to make people aware of the unknown town.
The author included the prologue to provide a sort of introduction of her home and the place, which most people seem to be unaware of. She recounts how her sister has <em>"assumed that the book on Mooreland had yet to be written because no one sane would be interested in reading it"</em>. Then, she also stated her own belief that <em>"there was so much more to the town than its trappings"</em>, which is in a sense why she decided to write the book.
