Book excerpt: "On Halloween night five years ago, Chelsea Dutton's college roommates were viciously stabbed to death, and Chelsea was critically injured ... Now in Boston, she lives a somewhat reclusive life, working from home as a medical transcriptionist and bingeing on mindless television shows ... When someone from her past reemerges, Chelsea starts receiving disturbing messages and worries that her every move is being watched. As the messages mount and her memories begin to return, she's led to a very terrifying and lonely place. But she needn't be afraid. She wont be alone there for long"--Amazon.com.
