When the Light Goes Out

Publisher's blurb:

Standing forgotten on the Oregon coast, a beacon for lost sailors helps conceal a town’s secrets, and an insidious evil. The Widow’s Peak Lighthouse has been a landmark for travelers near the Witch’s Cauldron State Natural Area for nearly 150 years. Closed to the public, it’s been the source of many local legends. Recently it went up for sale, and the bidding between the locals and a reclusive millionaire was vicious. However, money won out over local interests, and members of the party have been hired to help with the restoration and study of the lighthouse. As they work to restore the building, they find more and more things that should not be.
