"Eilean Eadar is a barren, windswept rock inhabited by a few hundred humans and sheep. Until now, the island was best known for the disappearance of three lighthouse keepers in 1919, a mystery that was never solved. But when a young man is found dead at the foot of the same lighthouse and the injuries are inconsistent with suicide, two detective inspectors are sent from Glasgow to investigate. Georgina 'George' Lennox is finally back from leave after a devastating accident and happy to be on the case with her partner, Richie Stewart, despite being greeted by hostile locals who seem determined to thwart their investigation. While they struggle to gather details surrounding the young man's death, George and Richie uncover more about the island itself, the community and their strange beliefs, all tied to a powerful, enigmatic priest. Richie wants to close the case, and head home to his family, but he hasn't heard the wolves at night or seen the dark figures at their window. George is certain there's something going on -- but can she trust her own instincts, or have the painkillers and sleeping pills she has grown dependent on impaired her judgment? But Eilean Eadar holds a far darker secret, and George's investigation will eventually lead her to a terrible truth that will threaten both her sanity and her life." -- Provided by publisher.
