Having at last recovered from the 2013 Boston Marathon terrorist attack, Klaryssa Mahr wants nothing more than to return to her life as a single mother and art history professor. When approached by a stranger who had discovered an unusual charcoal drawing in her family's archive, Klaryssa's world is again upended when she recognizes this simple work of art as anything but a random oddity scribbled by an anonymous artist. She knows that the sketch was drawn by Michelangelo, and it is intimately linked to an epic masterpiece that vanished over five centuries ago.In short order, Klaryssa finds herself steeped in the savage world of Matthias and Stephan Huber, scions of a family that has orchestrated the trafficking of priceless art for generations. Klaryssa's quest to establish the provenance of a once-lost treasure leads to the unveiling of a sprawling crime syndicate whose operational ground zero is located along a desolate expanse of sand known as Race Point.
