Necrosis by Lucy Smoke

In the pitted depths of despair, a flame burns ever eternal – a Daimon’s strength to do what she must.
Nerys is determined to rescue Coen. She and her potentials make the treacherous journey back to the place where it all began. Matric’s Kingdom—Euron. But what lies in wait is something much deadlier than the recently deceased king.
A new darkness has escaped its confines, ready to reign and wreak havoc.
Torture.
Pain.
Loss.
The world begins to unravel and with it, the Gods’ plan for Nerys is revealed. Though it may mean the destruction of her own life, Nerys will be the weapon to end the coming war.
