Last to Know [EPUB ebook] 

Townsend Heights is the perfect small town, just the kind of place Tasha Banks longed for when she left her big-city career for full-time motherhood. But now her dream is turning into a nightmare as a serial killer stalks Tasha’s friends. One by one they are dying in horrific ways, and terror is transforming her peaceful existence into one of fear and foreboding . . . where evil lurks behind the mask of a familiar facea face that may be the last one Tasha ever sees.
