House of mystery

"The House of Mystery has been temporarily relocated to the Space Between, where death rules and the body count continues to rise. Meanwhile, Fig, Peter and Jordan venture out into the city of ghosts to visit the long-abandoned Pathfinder's Academy where the most desperate specters wail and gnash. But the Pathfinder's Academy holds more than ghosts--it also contains ancient dark secrets that will change Fig's life forever. Will Fig and Peter find a way out? And to make matters even worse, the House of Mystery's previous owner has returned to reclaim what's his."--Amazon.com.
