A headless doll. A deserted island. A haunted lighthouse. Twelve-year-old Jennifer's summer vacation is not going anything like she expected it to. She's staying with her Aunt Liv, who lives on an island off the coast of Maine. The island is mostly famous for its lighthouse, which is rumored to be haunted by a ghost. Aunt Liv is an artist who specializes in making one-of-a-kind dolls. She also runs a doll hospital so people send her their dolls from all over to repair.

Jennifer notices some creepy things about the house, like flickering lights and something that sounds like faint whispering. Then one of the dolls that Jennifer has been helping her aunt work on is found broken. A neighbor girl tells Jennifer that her aunt's house is haunted by a ghost who's looking for her lost doll. Jennifer doesn't want to believe her. But after more dolls are broken, she starts to get scared. What if the ghost is real?
