[set immediately after Lord of Shadows by Cassandra Clare, contains Dark Artifices, Infernal Devices and Tales from the Shadowhunter Academy spoilers] 'The boundary separating the mortal world and Fearie hit Mark like a wall of iced water. He clung to his horse's mane, leaning low on its back to gaze down at the soaring fields and twisting, blood-red rivers that ran beneath them.' With each shadowhunter still reeling from loss, the Blackthorn family is almost falling apart. Julian and Emma must put hundreds of miles between them just to survive. Mark is torn between Christina and Kieran, Faerie and the Shadow World. Ty is hurt. Kit is lost. Everything is spiralling out of control, and the stakes are higher than ever. But, as always, there is hope for the Blackthorns- when they are torn apart, they will give anything to come back together.
