A year after Amelia Magic School’s darkest secrets were exposed, the campus has finally returned to peace—until its first-ever transfer student arrives. Elnar brings with him the shadow of forbidden magic, and when the school’s protective Four Jewels are destroyed, black magic begins spreading again. The surviving members of the Five must rely on clues, dreams of their lost friend Ah-reum, and a growing alliance with legendary magical creatures to confront an enemy armed with the Devil’s Grimoire. Expanding the world of the first novel, this sequel combines mystery, puzzles, magical combat, and Korean-inspired creatures in a youth-authored adventure about loyalty, courage, and defending a world already scarred by betrayal.
