Guess Who? #15

As usual, here are the rules: this is an (educated) guessing game where every Friday I post five facts about an author, each one a little more revealing then the previous one. I'll give you the weekend to try and figure out who I'm talking about, and the Monday following, I post the answer:

1. Female author.
   
2. Lives in Arizona.
3. She wrote a bestselling series with one word titles.
4. Pillow, glass, chair.
5. This author's last name begins with "Mc".
