Mistwalker

When Willa’s brother dies on the family fishing boat, her father forbids her from stepping foot on the deck. But her family needs her, and she’ll do anything to help out – even going to see the Grey Man, the legendary spirit who haunts the lighthouse, controlling the fog – and with it, the fate of any boat within 100 miles. But what Willa finds isn’t a spirit at all, but a boy trapped inside until he takes 1,000 souls.
