The Assassin's Blade

Overview

The Assassin's Blade gathers a set of novellas that precede the main action of Sarah J. Maas's Throne of Glass series, following Celaena Sardothien in the years before she becomes the character readers meet in the first novel. Rather than a single continuous story, the collection is structured as discrete episodes, each following the young assassin on a different job or entanglement.

Read together, the novellas trace a gradual hardening: an apprentice assassin taking on increasingly dangerous work, testing the limits of her guild's loyalty, and confronting the costs of the trade she has been raised into. The book functions as both an entry point for new readers curious about the series' world and a deepening of backstory for those already invested in Celaena's later arc.

Origins and Place in the Series

Maas wrote much of this material as self-published prequel content before it was collected and released alongside her growing Throne of Glass readership, and the book is frequently recommended as a starting point for newcomers despite following chronologically before book one. Its popularity tracks closely with the series' broader success and with Maas's subsequent Court of Thorns and Roses books, both of which helped cement her as one of the more widely read authors in contemporary YA and New Adult fantasy.

Thematically, the novellas are less concerned with worldbuilding than with character: they examine how someone raised inside a criminal apprenticeship comes to define her own sense of loyalty, self-worth, and morality, often through violence rather than in spite of it. That tension between a sympathetic protagonist and her profession is central to the series' appeal and to the questions the prequels raise about culpability and survival.

Why The Assassin's Blade Has Been Challenged

Objections to the book have generally centered on its violent content — detailed depictions of killing, torture, and assassination carried out by a teenage protagonist — as well as scenes involving human trafficking and sexual content that some reviewers consider mature for the younger end of the series' YA readership. Critics have also pointed to the book's morally ambiguous framing of murder as a skill to be admired. This catalog tracks 7 states and 13 districts in which the title has faced a formal challenge or ban.
