Vivian Lawrence was born into old-money Boston, but when her family fortune vanishes so does her carefully curated life. Desperate, she turns to an old family legend that ties her to the Knox and its inheritance, searching for a way into the exclusive secret society. She doesn't expect that entry to come in the form of Peter, a charming Knox insider with movie star good looks and just enough roughness to his charm to make Vivian weak in the knees for the first time in her life. Far from Boston's glittering elite is newcomer Taylor Adams, a restless young nurse eager to distance herself from her simple Outer Banks upbringing. When the effortlessly glamorous Vivian lands in her ER after a suspicious fall, Taylor is instantly captivated. But then Vivian abruptly disappears without a trace, and Taylor's search for answers pulls her into the Knox itself-as their new employee. The further Taylor goes into the Knox's orbit of unimaginable wealth and sordid history, the more the mystery of Vivian deepens. As Taylor will soon discover, more so than money or status, secrets are The Knox's currency.
