Juno McKay intended to avoid the nearby campus of her alma mater during her fifteenth reunion weekend, but she just can't turn down the chance to see her longtime friend, Christine Webb, speak at the Penrose College library. Though Juno cringes at the inevitable talk of the pregnancy that kept her from graduating, and of her husband, Neil Buchwald, who ended up in a mental hospital only two years after their wedding, Juno endures the gossip for her friend's sake. Christine's lecture sends shockwaves through the rapt crowd when she reveals little-known details about the lives of two sisters, Eugenie and Clare--members of the powerful and influential family whose name the college bears. Christine's revelation throws shadows of betrayal, lust, and insanity onto the family's distinguished facade.

But after the lecture, Christine seems distant, uneasy, and sad. The next day, she disappears. Juno immediately suspects a connection to her friend's shocking speech. Although painfully reminded of her own experience with Neil's mental illness, Juno nevertheless peels away the layers of secrets and madness that surround the Penrose dynasty. She fears that Christine discovered something damning about them, perhaps even something worth killing for. And Juno is determined to find it--for herself, for her friend, and for her long-lost husband.
