Swords of Stone

In the land called Coin, it is always night. There is talk of war from the south, as a dragon circles over a volcano, and forces of tyranny come marching from the north. Among the chaos, the Emperor of Day and his army of four unlikely heroes (Cephas, Levi, Esau, and Bartimaeus), are on a mission to liberate the oppressed, and enlist as many as possible to their cause before it's too late-and ultimately bring Day to a land that has only known darkness.
