Sam and Dean Winchester have spent their lives on the road, battling
every kind of supernatural threat. Over the years, after dozens of
bloody adventures, they have faced everything from the yellow-eyed demon
that killed their mother to vampires, ghosts, shapeshifters, angels and
fallen gods. With the help of allies--both human and
supernatural--they've discovered that every threat they vanquish opens a
new door for evil to enter in.
Visitors passing through Brownsdale, Kentucky are often never seen
again. The locals claim that it's easy to fall victim to the vast local
caves if explored unaided, but when two young girls go missing Sam and
Dean set out to investigate.
As the brothers start to suspect something far more sinister in the
town, and possibly lurking in Mammoth Cave, they realise that someone is
determined to protect the town secret--even if it means killing Sam and
Dean himself.
A brand-new Supernatural novel, set during season 10, that reveals a
previously unseen adventure for the Winchester brothers, from the hit TV
series!
