The capital has fallen, and darkness reigns over Ravka. From his shadow throne, the Darkling wields unimaginable power, threatening to consume the entire nation.

Deep beneath the surface, a weakened Alina Starkov—the Sun Summoner—hides within an ancient labyrinth of tunnels and caverns. Under the watchful eyes of the Apparat and zealots who worship her as a Saint, she must bide her time. But Alina's heart and plans lie elsewhere.

With the fate of Ravka hanging by a thread, Alina must escape and embark on a perilous quest to find the elusive firebird—the last of Morozova's amplifiers. Joined by Mal, the disgraced tracker, and the scattered remnants of a once-great magical army, she must forge new alliances and set aside old rivalries.

As Alina delves deeper into the Darkling's secrets, shocking revelations about their intertwined past emerge, challenging everything she thought she knew about the bond they share and the immense power she wields.

But claiming the firebird could come at the ultimate price. Will Alina sacrifice the very future she's fighting for to save Ravka from destruction?
