When Arahna unrolls a centuries-old map in her bedroom, she and her adventurous friend Talfen form the Horizon Seekers Club, determined to uncover every hidden corner of the globe. From the whispering peaks of the Swiss Alps to the vibrant markets of Marrakech, they craft miniature landmarks, sample spices, and record distant chants—each chapter a fresh window into a new land. Armed with guidebooks, clay models, and boundless imagination, they compete for a virtual-reality expedition grant that will transport them beyond classroom walls. "Discovering Hidden Horizons" is a playful, comical journey of friendship, curiosity, and the thrill of exploring our vast, beautiful world.
