Four students. Three temptations. Two worlds. One very slow turtle. When Park Min-jun and his classmates stumble through a mysterious cabin during a school field trip, they discover Koreanna-a realm where Korean mythology lives and breathes, where elves wear hanbok and mountains dance. But this isn't the magical paradise they expected. Every citizen is trapped, staring at glowing crystal tablets, unable to see the world crumbling around them. The noble White Tiger, guardian of culture, family, and soul, is imprisoned in an endless scroll of false reflections. And the brilliant Lady Thorn doesn't rule through fear or ice-she rules through notifications, updates, and the most powerful spell of all: being too busy to think. As the four teens race to save the Tiger, they each fall prey to Koreanna's digital enchantments-infinite comics, perfect game worlds, every song ever sung. Only the ancient Turtle, moving too slowly for anyone to notice, continues the quest. Because sometimes the only way to save the world is to move at the speed of wisdom, not wifi. A thrilling adventure that asks the question every modern teenager (and adult) needs to face: What if the real magic was paying attention? "A wildly inventive fable that feels both timeless and urgently modern. Part Narnia, part Black Mirror, wholly unforgettable." "Finally, a fantasy that understands our real modern curse isn't evil-it's distraction." Perfect for fans of The Chronicles of Narnia and The School for Good and Evil, with a uniquely Korean twist that speaks to our hyperconnected age. Will you put down your phone long enough to save two worlds?
