Sometime, somewhere, someone is searching for answers . . .. . . in a thirteenth-century castle. . . on a train to a concentration camp. . . in a New York city apartmentHidden within the binding of an ancient text that has been passed down through the ages lies the answer to one of the heart's eternal questions. When the text falls into the hands of Rabbi Kalman Stern, he has no idea that his lonely life of intellectual pursuits is about to change once he opens the book. Soon afterward, he meets astronomer Isabel Benveniste, a woman of science who stirs his soul as no woman has for many years. But Kalman has much to learn before he can unlock his heart and let true love into his life. The key lies in the mysterious document he finds inside the Zohar, the master text of the Kabbalah.
