Queen of Air and Darkness

The Shadowhunters are still grieving their latest losses, and the Clave is close to splitting apart. A hardline faction called the Cohort, led by Horace Dearborn, is taking control and pushing a doctrine of Shadowhunter supremacy. The Inquisitor is dead, and the Blackthorn family is divided by grief and by the threats pressing in on it.

In that climate, Emma Carstairs and Julian Blackthorn are sent on a dangerous mission to Faerie. They are pulled into a feud between the Seelie and Unseelie courts, and the trail leads them further, into an alternate universe called Thule.

Emma and Julian also have to live with feelings they are forbidden to act on, because of the parabatai bond that ties them together. Cristina, Mark, Kieran, Ty and Kit each follow storylines of their own, and veteran heroes from earlier Shadowhunter books return to lend a hand.

This is the third and final book of The Dark Artifices, a young adult urban fantasy in the Shadowhunter world. It follows Lady Midnight and Lord of Shadows and brings the series' long arcs to a close, with family, loyalty and prejudice at the centre.
