Help on my character analysis essay!

Hello
I’ve been assigned to write a character analysis essay on one of the characters from Ray Bradbury’s novel, The Martian Chronicles. I have chosen Ylla as I find her the most interesting. I have started to write my introduction but I just don’t know if its right or not and how to end it before I start writing the middle paragraphs..

The character I have chosen to study from Ray Bradbury’s novel, “The Martian Chronicles,” is Ylla, a Martian housewife who is plagued with an overbearing husband and dreams of earthmen landing on Mars.

Should I change this? What other sort of information should I add to the introduction? How can I get this introduction to hook the reader?
Thanks for any help (:
