Adventure awaits in the Five Kingdoms – come and claim it in this start to a new series from the number-one New York Times best-selling author of the Fablehaven and Beyonders series.

But when a spooky haunted house turns out to be a portal to something much creepier, Cole finds himself on an adventure on a whole different level.
