The criteria for being a favorite author has different parts to it, it really depends. So there are a few categories of favorite authors.
There are books I adore because they are so well put together and beautifully written that I feel the need to savor each page, like dark chocolate. I tend to read these books more slowly to make the book last longer. I will also reread these books because they are usually few and far between. My dark-chocolate authors include: Tracy Chevalier, Charlotte Brontë, Betty Smith, and Charles Dickens.
Then there are authors that write such fun books that I can't help myself, I need to devour them. These almost always fall into the chick-lit category. I wouldn't call these classics, but the books are a lot of fun and these authors are my go-to when I need to cheer up or lighten up, like when I watch Disney. My cheer-up Disney authors include: Sophie Kinsella, Charlaine Harris, and Janet Evanovich.
The last category consists of authors that are able to sweep me away to another world in such a complete way that I will miss the world revolving around me. These authors include: Brad Parks, Christopher Pike, Stephen King, and Ken Follet.
