FIRST EDITION / FIRST PRINTING  ACE FANTASY
Like new and unread with minor shelf wear to cover.
The archdemon Atamar has not been pulling his weight in bad deeds, and he and his junior demons have been banished from Hell until they can collect recruits for Hell. But when the demons find a team of American archaeology students, they realize their ideas of bad deeds are hopelessly out of date.
