Ron Goulart’s Harry Challenge series is a two-book run from the mid-1980s. The Prisoner of Blackwood Castle came first in 1984, and The Curse of the Obelisk followed three years later in 1987. Both titles point to an adventure-flavored series with a gothic or mystery bent, given the castle and obelisk settings.
The series is short at just two entries, and readers can get through the complete Harry Challenge story by reading them in publication order.
