The Temple Elders send Kal and Daine through a portal as bait for the Reaper's army of arrochom, back to the world where they first met. Daine's world. The Reaper's world. A cold and hostile world on the brink of extinction. Can a plan forged by an old mage before they were born really help them defeat the being who destroyed Daine's world, or will The Reaper win yet again? The Black Gate is the second volume of the Twin Worlds trilogy, an epic tale of swords and sorcery, travel and adventure, love and loss, good and evil. But most of all, a tale of adolescence and growing up.
