From publisher blurb:
FOR A THOUSAND YEARS the Dark Lady, a sorceress of ancient Baghdad, has lain in mystic stasis, her mind imprisoned through the power of a legendary gem.
FOR A THOUSAND YEARS a hideous race of parasites has chafed at the wards barring them from Earth, and has labored to aid the Dark Lady who could free them.
FOR A THOUSAND YEARS the Servants of the Dark Lady have sought to destroy the mystic opal called 'Heart of Darkness,' to release their evil mistress into the world once again.
FOR A THOUSAND YEARS the Brothers of Ahmed have dogged the heels of the Servants, seeking the knowledge to destroy the Dark Lady for once and all time.
