A new author for me. The writing was crisp and the story was fast paced. Emma, an ex FBI agent goes to a small island after her sister Molly dies. The police are determined to rule her death a suicide, but Emma doesn't believe them. As she investigates she learns secrets about her sister, and also about the people on the island.There are some surprises that just had my jaw dropping. I wasn't expecting them. This was a really good mystery/thriller.
