Displeasure Island — Alice Bell

In the hilarious follow-up to Grave Expectations, Claire and the gang are back, getting their timbers shivered by a mystery involving feuding ghost pirates, buried treasure, and murder...

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.
