The truth can be deadly. Brylee Branson's best friend and boyfriend have fallen victim to a horrible curse that haunts her home.

But time is not on her side, because Lynley's illness is spreading rapidly. Confused and scared, seventeen-year-old Brylee must confront a new ghost in the house she has never spoken to before. This spirit is not a Brown relative and makes no promises to help them … unless she can re-unite her with a loved one. The fate of those she loves now rests on her. Can Brylee put the pieces of this puzzle together in time to save them? Or will the Brown house claim another victim? The Visitor's Series continues to scare and entice its readers with this gripping second book.
