Marked By Shadows by Lissa Kasey

Who would have thought a crafting retreat could turn deadly?
An escape from the exciting life of New Orleans ghost tours sounded like a good idea at the time. Micah invites Alex along to experience a few days of crafts, fabrics, and hanging out with friends. Except the group is more interested in ghost hunting than costume making.

When a couple from the group go missing, Alex claims to see something in the dark. As Micah’s troubled history begins to catch up with him, he realizes that the shadows followed them from New Orleans. He’s not sure if it’s their demons causing trouble, or someone human who is murdering competition.
