Alanticorn. An ancient city long since cast to the realm of fantasy by most rational ponies. But for Kessa Forelock, it's very real and she's spent years following the clues left behind in forgotten books and scrolls to bring her to the deserts of South Zebran. A discovery there casts Kessa and her best friend Cander into a previously unknown world of deception, secrets and forgotten lore as they race to stay one step ahead of a dangerous unicorn who seeks to use the power of the lost city to achieve his own goals.
