The final book of the Sovereign of the Seven Isles begins in the mountains of Andalia with Alexander—wounded, surrounded and fleeing for his life. Isabel learns that Phane can use her link with the darkness for his own, terrible ends. And Abigail rallies the Coven to face the Sin’Rath, a threat now magnified a hundred fold. Battle rages across the Seven Isles, and Alexander Reishi stands at the center of it all. As forces converge on the Nether Gate, he departs on a desperate quest to free Isabel, kill Phane and banish the Shades for all time.
