Stella And Grim "BLOOD FOR BLOOD"

Stella thought her visit to the lighthouse would be quiet—just a weekend with her reclusive grandfather by the sea. But when he tries to sacrifice her to an ancient sea-born manifestation to extend his own life, Stella is thrust into a nightmare where fear takes form and the ocean hungers for more. Her only ally is Grim, a mysterious dockhand with secrets of his own and a past tied to the same dark force. Together, they must outwit the horrors that rise from within and beneath, uncover the truth behind the emotional monsters plaguing humanity, and make a dangerous bargain that could save the world—or doom it.
