Civil war is about to engulf the fae. The last time it happened, in 1666, it led to The Great Fire of London. This time, the presence of a mysterious third party promises disaster. After saving the British Bureau for the Arcane from its enemies, Arlo Austin and his son Tayn are back. While they recovered in New Zealand, the Bureau has undergone huge changes, thanks to its new leader, Sylvia Kent. Having eliminated corruption, the Bureau is leaner, more efficient.

Except that’s also the problem, he could be another source of corruption. It looks like the Bureau’s famous warrior compromised its neutrality in the past - and the consequences are dire. Especially when Tayn is drawn into the fae’s political machinations, on the opposite side. Book 2 in the noir fantasy that's been described as "the fantasy version of Men in Black".
