Black Hallows - Andrew Naisbitt

The Black Hallows is on the rise once more.Its existing conduits may have been eliminated but new vessels have opened up to its malign influence.
In the Blasted Lands, a creature born from the fusion of a fyre guardian and a giant insectoid makes its lair in ancient chambers where the sacred agnarim dragon eggs incubate.
The former Queen of Cuscosa lives on in the body of her faithful blue-skin thrall, waiting for a transformation fuelled by the Hallows.
A remnant of Kaldorans appoints a new leader willing to embrace the power that will re-instate them as an irrepressible force in the north.
And there is another power stirring in the marshlands of the east - an insidious and mysterious overlord known as 'The One'. He seeks to recruit an assassin from each dominant race, intent on attacking the kingdoms from within.
Such is the cauldron of intrigue stirred up amongst the peoples of Varchal, yet the Black Hallows does not care. It thrives on chaos, and anything that promotes the destabilisation of the Imperious Crescent will serve its ends.

Meanwhile, Tayem Fyreglance has abdicated the Dragonian throne. Her sister rules in her place. She imagined she might recover in the land of the Gigantes, protected from the ravages of the Hallows. That is until a call comes from the Dreamworld, urging her to once more seek out the queen of dragons, Agathon. Their fates become intertwined with upheavals in the Blasted Lands, and ultimately, the machinations of the Black Hallows itself.

In this, the second novel in the Black Hallows trilogy, four queens tread the path of destiny, all hurtling towards a conclusion they may not survive.
