"Within the hexed walls of the fortress, Dan and his companions are plagued with unsettling questions...questions whose answers will require a deeper infiltration into the secret recesses of the centuries-old castle, answers which will involve confrontations with the citadel's animate and inanimate residents, and answers which will entail encounters with the savage beasts of the forest. Is Dan's brother, William, alive and a prisoner of the Reclaimers? Will the travelers survive the spellbinding powers of the half-man and half-serpent creatures? Will the rescuers breach the spatial boundaries of the parallel world and return home?"--from publisher's description.
