A Lethal Legacy

Douglas Island sits off the coast of New York
State, its imposing cliffs warning away visitors. Still, Finn Douglas
has big plans for his inheritance and the rambling manor house that
dominates the landscape. He has a vision to turn the island into a
resort getaway for overworked city dwellers. But when the broken body of
his business partner is found at the base of the rocky escarpment, he
fears it wasn't an accident.

Special Agent Craig Frasier agrees
to help his cousin Finn by investigating and, with psychologist Kieran
Finnegan at his side, heads to the island. As Craig and Kieran delve
into the history of the Douglas estate, they discover that the property
comes complete with strange lore and a blood-soaked past. Something evil
seems to be lurking in the caverns that run beneath the stony ground.
Is there something on the island that someone is willing to kill to
protect? Kieran and Craig take on a dangerous search for the truth,
where one false step could send them plummeting to their deaths, and one
wrong turn could bring them face-to-face with a killer.
