The Sapphire Portal (The Gates of Good and Evil #4)

The world of Santhenar has fallen

Most of the old allies are dead or captured, and the conquering Merdrun are carving Skyrock into a gigantic tower, with a sapphire-clad tunnel at its base. Is it a horrific new weapon to cleanse the world, so they can take it for their own? Only their arch-sorcerer, the sickening, life-drinking magiz, Dagog, knows.

Karan, Flydd and their broken allies have only thirty days to find the answer. Thirty days to unlock nine-year-old Sulien's hidden memory and reveal the Merdrun's one fatal weakness. But Sulien has been abducted by the magiz, who needs her talent of far-seeing for his monstrous conspiracy.

To save her daughter's life, Karan will have to break into a compound guarded by 150,000 enemy troops and every magical device known to the enemy.

Assuming she can get past the traitor in the allies' ranks.
