Free Monday Mystery

I'm signed up for a lot of the newsletters that showcase free Kindle books. When I'm feeling a little light in the wallet, it comforts me to know that I can still have new books to read without spending any money. (I spend a lot of money on books when I have it to spare, so I'm not one of what a friend of mine calls a "greedy grabber" who won't spend money on books and just slurps up all the freebies.)
Today it's Mystery Monday, and I snagged this thriller, the first of a series set on the Oregon Coast. I'm still new to the Pacific Northwest, so I'm eager to see how it's depicted in The Gray and Guilty Sea.
