What is an arguable thesis that presents the literary analysis of Hatchet, Number of the Stars, or The Breadwinner with main points?
This is a very broad question. It sounds like you can focus in on just one of these books in your essay. Though I cannot draft a thesis statement for you, I can give you a few pointers about essay writing, and I can also help you brainstorm a bit.
As you write an analytical essay about a book, you should focus on a specific interpretation of the book. Rather than merely retelling the story, you need to focus on an issue that interests you, make a point about it (the thesis), and back that point up with a number of examples from the text. See the link below for further information about essay writing.
Hatchet by Gary Paulsen is about a boy, Brian Robeson, who gets stranded in the Canadian wilderness. As he learns to survive and rely on himself, he also comes to terms with his parents' divorce. A good thesis statement about this book might explore how Brian's experiences in the wilderness help him overcome his guilt over his parents' break-up. Another might examine Gary Paulsen's use of dreams and flashbacks in order to advance the story.
Number the Stars by Lois Lowry is about a girl who helps smuggle her Jewish friend out of Denmark during World War II. Good thesis statements about this book could explore racism and xenophobia or examine the ways children, who do not traditionally have much power, can make a mark on their world.
The Breadwinner by Deborah Ellis, is about a girl in Afghanistan whose father goes to prison. She dresses up like a boy and goes out to work to support her mother and siblings. Thesis statements about this book might explore the power of the powerless, feminist issues, or the strength of family bonds.
