Sarah J. Maas started writing what would become Throne of Glass when she was sixteen, posting chapters on FictionPress. The series launched in 2012 and established her as a force in young adult fantasy. A Court of Thorns and Roses (2015) began a shift toward adult romance fantasy—the series has sold over 13 million copies and spawned a Hulu adaptation in development. Her Crescent City series blends urban fantasy with her signature worldbuilding. Maas writes sweeping romantic fantasy with intricate magic systems, morally complex heroines, and memorable romantic leads. Her books are doorstoppers; her fans are devoted. Critics note her pacing issues and purple prose; readers counter that they've read ACOTAR six times. She lives in Pennsylvania with her husband, writer Josh Maas, and their son.
