Specter of the Spirit — Tammy M. Yourzek

It's been a really, really bad year for Katie Martin. First her older brother Ty was killed in an accident, then she searched for him inside and eerie video game...and now she has the scariest nightmares ever. Desperate to stop the bad dreams, Katie re-enters the game with her younger brothe and her friend Jessica, where they become characters in a fantasy story set in the Old West. Together with a mysterious young man named Zack, the three friends try to hunt down the objectives of the game: a haunted house, a very strange treasure, and a giant jewel. Any one of them could lead to Ty...or Grevnon, the evil spirit that haunts their nightmares. Katie begins to think that their friend Zack might not be a friend after all. How can they get out? Or are they doomed to stay in the game forever?
