When does an empire fall?

The Seven Satrapies have collapsed into four-and those are falling before the White King's armies.

Gavin Guile, ex-emperor, ex-Prism, ex-galley slave, formerly the one man who might have averted war, is now lost, broken, and trapped in a prison crafted by his own hands to hold a great magical genius. But Gavin has no magic at all. Worse, in this prison, Gavin may not be alone.

Kip Guile will make a last, desperate attempt to stop the White King's growing horde. Karris White attempts to knit together an empire falling apart, helped only by her murderous and possibly treasonous father-in-law Andross Guile.

Meanwhile, Teia's new talents will find a darker use-and the cost might be too much to bear.

Together, they will fight to prevent a tainted empire from becoming something even worse.
