This middle section of your introduction paragraph needs to do a fairly simple job: make sure your reader knows which text you'll be citing. Here is the information that should appear in this part of your introduction:
The name of the text or texts (full length texts, like novels and plays, should be italicized; short length texts, like short stories or poems, should be in quotation marks).
The author(s) of the text(s). The first time an author is mentioned, be sure to include their full name, and refer to them by last name only every time afterwards. (Be sure to double check your spelling: nothing makes you seem like you're not invested in your argument like misspelling the author or title of the book you're writing about.)
If there is a single element that you're focusing on throughout your essay (for instance, a single character), then make sure that element is mentioned in this section as well.
This part of your introduction should be short: one sentence is usually enough, more than two sentences is almost never necessary. You can frame these sentences by explaining how the text (or the specific element) is relevant to the idea in your hook.
