Tower of God Volume One

Rachel disappears through the gates of a mysterious Tower right before Bam's eyes, warning him to forget her as she goes. Unwilling to let her go, Bam enters the Shinsu-filled Tower himself, beginning a climb through countless floors — each as vast as a continent, with its own geography, culture, and guardians — that test his strength, wit, and resolve at every turn.

S.I.U.'s webtoon-turned-graphic-novel builds an intricate, ever-expanding fantasy world, as Bam's search for Rachel gradually uncovers unsettling gaps between what she told him and what actually happened.
