Did her parents send her to the Purgatorium to help her or punish her? A teen who feels guilty for her sister's death is sent by her parents to what she thinks is a vacation retreat but is soon at the mercy of a doctor's experimental treatment. After undergoing one bizarre experience after another, the teen gets lost on the haunted side of the island and wonders if her parents meant to help or to punish her. Some readers have compared this young adult psychological thriller by USA Today bestselling author Eva Pohler to Shutter Island and Lost. Captivating, chilling, and very mysterious. You will find yourself holding your breath. I truly wasn't sure what was going to happen but let's just say it will blow you away!—Southermermaid85, Amazon Reviewer????? Awesome series!! Could not put the books down!—Kris MacGillivray, Amazon Reviewer????? This story had me in a roller coaster of emotions and worries. I was constantly in edge thinking what will happen? Is this real or part of the therapy. Eva did a wonderful job keeping me on my toes and making my mind work on overdrive. So many references from studies I myself have looked into. I loved!—Mariela, Amazon Reviewer?????
