Where the Heart Is

Where the Heart Is is a fiction book.
I chose this book because after hearing about the general storyline from a family member I was interested and wanted to know the whole story. The book is about a young girl named Novalee Nation who early on in the book gets stranded at a Wal-Mart in Oklahoma by a guy who was too bothered to wait for her. If that's not bad enough she's also broke and pregnant. Having nowhere else to go, she figures out a way to live in the Wal-Mart. A short two months later she has the baby in the store and her hidden living situation is brought out in the public. The birth in the store caught the attention of people across the nation. Throughout the book she meets Sister Husband who in the end becomes her closest ally and the closest thing she has to family, Moses Whitecotton who becomes her mentor and Forney Hull who becomes her best friend and boyfriend. She picks up hobbies and friends and has an unwaivering determination to gain knowledge.
The significance of the title Where the Heart Is is that Novalee learns that you can learn to love a place and the people in it even when starting from nothing. Novalee finds where her heart is and who it's with.

3. Why did you choose 7 as her unlucky number when most people see it as a lucky number?
