The Gates of Heaven (Seven Brothers, 3) by Curt Benjamin

The magnificent Seven Brothers series continues with The Gates of Heaven...Even as Prince Llesho's hard-won alliances are threatened, he is caught in a race against time and the evil sorcerer Markko, as he struggles to complete his prophecy-fulfilling quest. Will the price of Llesho's quest prove too high to pay? For every step forward must be paid for with the lifeblood of those he holds dear. And even with gods and legendary creatures championing his cause, will he reach his goals too late and too weakened by the struggle to stand against both the enemies he knows and those who have not yet been revealed?
