Art historian Nora Barnes and her husband, Toby Sandler, are visiting West Ireland for a family reunion. During a morning walk through a deserted village on Achill Island, Nora stumbles upon a body―her notorious uncle Bert. When a clue singles out her mother as the likely suspect, Nora and Toby are on the case to clear her name. Whether in a barroom brawl or the sauna of a swingers’ club, Toby has Nora’s back. As they search, the dead of Achill seem to speak from graveyards, ruined churches, and megalithic tombs. A second murder makes it all the more difficult to connect the dots. And when Nora and Toby become the next targets, their own survival is at stake.
Art history professor Nora Barnes and her husband, along with her parents and sister, are vacationing on Achill Island, a little stunned to find that Nora's Uncle Bert the Bastard and his family are there, too. When Nora finds Bert's body, she's afraid that her mother has finally snapped and attacked the brother-in-law she's always hated. As Nora and friends explore the island, she finds yet another dead body--but were they killed by the same person? And who was that person, as Nora stubbornly refuses to believe the murderer(s) was a member of her family?
