Julian and Emma are on their travel year when the Clave sends Julian a message: clean up Blackthorn Hall or ownership reverts back to the Clave. Amidst the clutter and disrepair they discover secrets that Blackthorn Hall has kept hidden for years... They find out something... or someone... else might be sharing the space with them. They’ll also entertain visitors like Jem, Tessa, Cristina, Mark, Kieran, Kit, Ty, Dru and more. Emma and Julian of The Dark Artifices move temporarily to London to fix up the crumbling Blackthorn Hall... only to find that among the various objects that belonged to their ancestors, there might be a spectral presence that wishes them harm... Secrets of Blackthorn Hall is an illustrated serialized epistolary novel by Cassandra Clare that was released online for free and now in print as part of the Seasons of Shadowhunters Kickstarter campaign. The story takes place roughly starting in January 2014—about a year and a half after The Dark Artifices—and takes course over the span of a few months—ending about a year before The Wicked Powers. It centers on the characters from The Dark Artifices but also delves into the history of those from The Last Hours and The Infernal Devices through books and old papers found in the house. For a better understanding of the story, please make sure you have read all of the Shadowhunter books released as of 2024, as there will be spoilers (TLH being the last book series released before this book.)
