Dive into the spellbinding realm of FlatWorld, where Edinburgh's own adventurous couple, Mac' and Mari MacKenzie, find themselves ensnared by an ancient and mystical chessboard, gateway to the sprawling Multiverse of endless worlds. In FlatWorld, which intriguingly mirrors a vast chessboard landscape, the couple is thrust into a race against time. They grapple with deciphering ancient scripts, separating myth from reality, all the while being ensnared in a looming conflict between the luminous White Tower, the stronghold of the Light's King and Queen, and the enigmatic Grey Court. To their astonishment, Mac' and Mari discover they've assumed the roles of the Dark King and his Grey Queen. Amidst the backdrop of fierce Goblorcs, valiant Knight Riders, stern men of steel, and Church-Cross Bishop armies gearing for war, Mac' and Mari's quest becomes twofold: find a way back to their beloved Edinburgh before FlatWorld claims them eternally and thwart an impending war that threatens to plunge both kingdoms into an abyss of endless darkness and turmoil.
