Frayed

Ava Hale will do anything to find her sister's killer...although she'll wish she hadn't. Because the harder Ava looks, the more secrets she uncovers about Kesley, and the more she begins to think that the girl she called sister was a liar. A sneak. A stranger. Ava can feel her whole life unraveling. If she didn't even know her own sister, then who can she trust? And that means that the murderer could be much closer than she ever thought possible...
