Darkdawn (Nevernight 3)

Pale Daughter. Kingmaker. Crow. A killer of kings. Gladiatii. Escaped slave. Infamous assassin. Mia Corvere is on the run.
After winning the greatest games Godsgrave has ever seen and giving the gift of murder as her victor’s speech, Mia is being hunted by every Blade of the Red Church and every soldier of the Luminatii legion.
Her mentor Mercurio has been captured and Consul Julius Scaeva stands on the edge of total dominance over the Republic.
Truedark approaches and if Mia is to have any hope of defeating Scaeva and saving her family, she must make a perilous journey across the Republic seeking the final answers to the riddle of her life.

Night is falling on the Republic for perhaps the final time.
