I wandered around the Kent Commons looking for a bookstore, and finally I stumbled upon a map of the place. Imagine my surprise when I looked and looked for a place that sells books and didn't find it. So, my expeddition to the Kent Commons ended with disappointment, as there was no evidence of any place that had books. At least the Federal Way Commons has a Borders in it.
Pros: Cleanliness, Ambience
Cons: Lack of Literary content
