A Salem's Cipher Mystery Series

Salem Wiley is a genius cryptanalyst, courted by the world's top security agencies ever since her quantum computing breakthrough. She's also an agoraphobe shackled to a narrow routine since her father's suicide. When her intelligence work unexpectedly exposes a sinister plot to assassinate the country's first viable female presidential candidate, Salem finds herself both target and detective in a modern day witch hunt. 

When agoraphobic genius Salem Wiley lands her dream job as an FBI cryptanalyst, she vows never to return to the witch hunt underworld, where ancient secrets encrypted by hunted women have the power to rewrite history. Her resolve disappears when sweet Mercy Mayfair, the child she is pledged to protect, is kidnapped. As the clock ticks, Salem must face the terrible truth that there is only one way to free Mercy: crack the unbreakable code of Stonehenge.
