Shadow House: The Gathering - Dan Poblocki
Some houses are more than just haunted... they're hungry.
Dash, Dylan, Poppy, Marcus, and Azumi don't know this at first. They each think they've been summoned to Shadow House for innocent reasons. But there's nothing innocent about Shadow House.
Something within its walls is wickedly wrong. Nothing -- and nobody -- can be trusted. Hallways move. Doors vanish. Ghosts appear. Children disappear.
And the way out?
That's disappeared, too...
Enter Shadow House... if you dare.
