Who’s In the Lighthouse? [EPUB ebook] 

Sadie has moved to Savannah for the summer. Her Pa has a job building a new harbor. Moving into an abandoned light keeper’s house Pa warned Sadie and Jimmy that the lighthouse was not a safe place to play. They can play in the yard, or they can go into town. However, they were never to go near the lighthouse and never go near the edge of the bluff. "A fall from the cliff to the rocks below will kill you, and the waves will carry your bones to Davey Jones’ Locker." Pa warned sternly. Soon Sadie would learn that the house held more secrets. Little brother Jimmy does not care he found a new friend living in his closet. Aunt Erin knows the secret, but Ma and Pa think it is just a joke. During the first full moon of October, a storm gathers and Pa’s ship is lost in the fog. Sadie wakes to find the old Lighthouse lit. "Who’s in the lighthouse?" she wonders.
