Heiress of Nowhere by Stacey Lee

1918. Orcas Island, Washington.

Lucy Nowhere has spent her eighteen years working on the vast estate of the eccentric shipbuilder who took her in after she washed ashore in a green canoe as a baby. But she has long wished for a life off the island, and in a matter of days, she is set to leave for college—and, for the first time, choose her own future.
Then she finds her employer’s severed head on the beach. Rumors swirl that a mischievous spirit and its minions, the sea wolves, have struck again. Lucy doesn’t believe in myths. She knows that a human—a human murderer—killed him. And when she is unexpectedly named heiress to the estate, she understands the next target is her.
Her closest friend, the estate’s vigilant young guard, begs her to escape while she can. But Lucy knows the only way she can discover who she is, and free the island of its curse, is to find the real killer—before she becomes the next victim.
