Entertainment Weekly reports that Rabia Chaudry has a written a book about Adnan Syed—one of the main subjects in season one of Sarah Koenig’s Serial. News of the book comes weeks after Syed was granted an appeal for a new hearing on his murder conviction of ex-girlfriend Hae Min Lee.

Chaudry is the co-host of the podcast Undisclosed who originally brought the murder case to Koenig’s attention. The book, titled Adnan’s Story: Murder, Justice, and The Case That Captivated a Nation, will “reexamine the investigation that led to Adnan Syed’s arrest, share his life in prison, discuss new evidence and possibilities that have since come to light, and review the recent court successes” including the reopened case, which Chaudry credits to Koenig’s hugely successful podcast.

In an official release, Syed said one of the first letters he received since being arrested in 1999 was from Chaudry, and “Since that time until now, she has believed in my innocence and been committed to my exoneration. There have been appeal hearings in which she is the only other person other than my mother who showed up… As someone connected to me, my family, my community, my lawyers, and my investigation, there is no one better to help tell my story, and no one that I trust more to tell it, than Rabia.”

Syed’s hearing date is still to be determined.

Adnan’s Story: Murder, Justice, and The Case That Captivated a Nation will be released in September 2016, via St. Martin’s Press.
