Step into the Shadows of Umbrae ... Miri's world at P.A.W.S. in St. Louis is falling apart. First, Danny is accused of stealing her opapa's charm. But before he can defend himself, he mysteriously disappears. Miri seeks Josh for help and advice, but he too has gone missing. Then Lilith has a vision - Miri dragged away by wolves. Miri needs answers, answers that she feels sure are hidden in the blank pages of the book of Argentum. With the help of Lilith, she travels to the ancient city of Safed. There, with the aid of a mystical rabbi and an outspoken werecat, her omama's story is slowly revealed. And Miri uncovers something else, a world hidden deep beneath our own - the labyrinth of shadows also known as Umbrae.
