The Slate Wizards

With Velak defeated, Grei turns to repair: reviving the fallen Faia, and bringing those who were turned to statues back to living form. It is the right work to be doing. It is also what creates the opening.

The Faia's absence had stripped the empire of the protection they provided, and something has been waiting on the other side of that shield. The Slate Wizards are immortal sorcerers who, in the book's own words, "have schemed to conquer Thiara for three hundred years." They have simply been waiting for the guard to drop, and now it has.

Grei is what stands between them and the empire. This is the concluding volume of The Whisper Prince trilogy.
