Spear of Heaven - Avaryan Resplendent, #2

Worldgates are a great magic and a great convenience: opening the way from one world to the next, and from one side of a world to the other. Now the mages of the Gates are exploring a new continent and forging new alliances, led by the Master of the Mageguild and the heir to the throne of Sun and Lion. Suddenly, the Gates begin to fall-and the Master and the royal heir are trapped in a hidden kingdom on the far side of the world, with no way out but through the broken Gates.
