Felix Kandel's book is a fascinating story about the search for the lost tribes, an incredible story that leads the reader from traditional legends about the insurmountable Sambation River and the mysterious Mountains of Darkness, beyond which the lost tribes live in prosperity, to the latest versions of modern researchers. The author included in his narrative not only historical information and testimonies of travelers, but also legends from different centuries, predictions of the prophets and interpretations of the sages of Israel, fantasies of dreamers, fabrications of adventurers, Jewish proverbs and aphorisms.
