Hanna is what you'd call mentally ill. She'd call it being totally crazy. After running away to Portero, Texas to find her estranged mother, Hanna thinks this new town can't be any crazier than she is. She's wrong. Portero is haunted with doors to dimensions of the dead, and protected by demon hunters called Mortmaine.

Hanna soon falls for a young Mortmaine named Wyatt, but when her mother is possessed by a murdering ghost, Hanna decides to do whatever it takes to save her, even if it means betraying the boy she loves. In the end no one will be left unscarred.
