Blood of the Chosen (Burningblade and Silvereye)

For centuries, the Dawn Republic has ruled over the land unopposed. No more.
Deep below the Gap, Gyre Silvereye discovered a city, hidden far from human eyes. There, the ghouls have dwelt for four hundred years in hibernation, awaiting the moment to wreak their vengeance on the Dawn Republic.

With their help, Gyre can finally see a way to overthrow the all-powerful Twilight Order. But the ghouls do not give their trust easily, and Gyre will need to secure the alliance of the human rebels to the south if they are to even stand a chance. And uniting the two won't be simple.

His sister Maya still fights for the Order. But after recent events, she is no longer certain where her loyalties lie. Chasing the origins of a mysterious artefact to a long-lost library, she just might find the truth - whether she is ready for it or not.
