Psychological Kidnapping

Working for the FBI, cryptanalyst and agoraphobe Salem Wiley vows never to return to the conspiratorial underworld her mother revealed to her. Until fieldwork draws Salem to an Ireland farm where a curious discovery has been unearthed: a near-perfect replica of Stonehenge in miniature—except for one extra stone engraved with the word mercy. When seven-year-old Mercy Mayfair, a child in Salem’s family’s care, is kidnapped, Salem knows it’s more than an unsettling coincidence.

Claire’s little sister Holly has been working on the millionaire’s playground of Martha’s Vineyard, going to barefoot beach parties and flirting with the local rich kids. But now she’s missing and none of the locals seem to care, including the police. They think a message Claire received is proof she’s safe. But Claire knows for a fact that her sister didn’t send it. What will she have to risk to find out the truth? Who are the locals protecting? And what does it have to do with another girl who went missing five years ago?
