Drang in Bloomington, MN

Drang Island. It's not supposed to be haunted...but no one told the spirits there...
Michael and his father head to a desolate island, the perfect place for Dad to finish the last chapters of his book of Norse stories. Before long, though, there is evidence that the rumors they've heard about Drang Island-about spirits, strange sacrifices and a serpent lurking in the ocean-might be true. A desolate island is not a good place to be trapped with the past.
This is the 2nd book in the Northern Frights series.
