Claire Hendricks can see ghosts, but she can't see herself having a fun vacation. Yet when her new friends/found family, Basher and Alex, insist, Claire and her dead BFF, Sophie, pack themselves off to a remote Irish island. This tempest-tossed isle is indeed full of noises: not only is the hotel where the gang is staying double booked with a posh private party, the island's crumbling old fort is being fought over by rival ghost pirates. In death, as in life, they're vying over a legendary stash of loot, supposedly hidden somewhere on the island or in the surrounding rough seas...

...which, inevitably, are whipped up into a terrific storm, stranding everyone—living and dead—on the island. Claire is already fighting off anxious And Then There Were None vibes before one of the other guests turns up murdered. With Basher distracted by a handsome Irish seaman and Sophie stretching the limits of her tether to flirt with a dead pirate with dubious intentions, it's up to Claire to solve the mystery of three-hundred-year-old buried treasure and figure out who's picking off party guests—before the whole gang meets a grim, Agatha Christie-like fate.
