Free Audiobook : Throne of Glass, by Sarah J. Maas

In a realm devoid of magic, an assassin receives an unexpected summons to the royal palace. While harboring no love for the ruthless king who sits upon his imposing throne of glass, she ventures forth not to end his life but to secure her own freedom. To earn her release from captivity, she must triumph over twenty-three formidable adversaries—murderers, thieves, and warriors—in a grueling competition to become the King's Champion.

Her name is Celaena Sardothien.

Throughout her perilous journey, the Crown Prince seeks to provoke her, the Captain of the Guard strives to protect her, and a princess from a distant land befriends her. Yet within the very walls of the castle, a sinister presence lurks, intent on extinguishing life. As her fellow competitors meet mysterious and untimely deaths, Celaena's quest for freedom evolves into a desperate struggle for survival. She embarks on a relentless mission to expose the malevolence that threatens to engulf her world before it consumes everything she holds dear.
