1st sentence of intro, name the author, the title, and a universal statement about the book. Make sure it's not a judgement.
2nd (and possibly 3rd) sentence(s): a thesis statement that is another statement. This one, however, "expresses one major idea about [the essay's] subject." (What a Good Thesis Is, 7)
NEXT, ask yourself to come up with two or more ideas / statements that back up your one major idea (your thesis).
Write them down ASAP. These will be your topic sentences, most likely.
Then, after each topic sentence, which needs to be a bold statement that backs up your thesis, you need to have a piece - or some pieces - of textual evidence to show the essay's readers how you came up with the thesis (and bold statements to back the thesis up). In other words, prove your one major idea and bold statements with proof from the text.
Now comes the fun part: after each piece of evidence, explain in analytical terms how the piece of evidence you've chosen can be interpreted by all readers to bring them to the one major idea and bold statements that you've made.
Conclude your lit. analysis in such a way that the reader would not "get it" until they've read your whole essay. Touch on your one major idea again, but differently than you did when you first introduced it.
