In 2013 Sarah J. Maas began publishing the Throne of Glass (TOG) series, based on a FictionPress story she posted in her teenage years to great success. What started as original fic online is now several thousand pages of an addictive fantasy adventure. Maas has since published 6 TOG books: Throne of Glass, Crown of Midnight, Heir of Fire, Queen of Shadows, Empire of Storms, and The Assassin’s Blade, a collection of 5 prequel novellas. A character-specific novel about Chaol, a Throne of Glass universe compendium and a sixth—and final—novel remain to be published in the series. Alongside this series Maas also began A Court of Thorns and Roses, a critically-acclaimed new adult fantasy series.
