A
series of
paperback books about the continuing sleuthing adventures of
The Hardy Boys. One book has been published each month since
1987. Finding the older ones can be quite challenging. It's getting kind of ridiculous.
This series started off on a hardcore note as Joe Hardy's longtime girlfriend Iola was blown up by a car bomb. Despite this tragedy, a lot of these stories have been pretty good, albeit homogenous at ~150-155 pages per book.
