Brother detectives Frank and Joe face the dangers of Black Bear
Mountain once again in the twentieth book in the thrilling Hardy Boys
Adventures series.
Frank and Joe are back on Black Bear Mountain, the scene of a previous
wilderness adventure and mind-bending mystery. This time, the brothers
are checking in on Dr. K, a friend they made during their first trip.
Dr. K is a fan of living off the grid, but he's been MIA long enough to
cause worry in the small mountain town. And so the teenage detectives
Black Bear Mountain relied on before have been called in to help once
again.
It's not a good start to the investigation when Frank and Joe's ATV is
put out of commission by a falling tree. Then their camp, including
their radio--their only way to contact the outside world--is destroyed
by wildlife searching for food. And when they finally reach Dr. K's
research station, they find his cabin has been cleaned out and
abandoned--the only current resident is an angry skunk.
Frank and Joe may have been better prepared for their second Black Bear
Mountain adventure, but they're not having any more luck this time
around. In fact, they've been downright unlucky. Is someone trying to
sabotage their mission? And if they are, how can the brothers stop this
invisible foe?
