The Boxers are finally getting organised — and not before time.
When a new Shadow Castle threatens the heart of Dalria’s second city, Artemis Macintyre and her team have one precious new advantage: after Kilrymont, they can now predict the ghostly castles’ destructive arc. But prediction is not prevention and each rescue remains a race against time. And every question they answer points to a more terrifying possibility – the castles are not random eruptions, but part of a vast design.
For Artie, the crisis has become personal in a way she can no longer deny. Marion Dean, the impossible ghost of Gamma Realm, may be a victim of the machine – or something far more dangerous. Meanwhile, Tearlach is under arrest, stripped of sympathy and surrounded by questions. If the old king thought it worthy to search for him across history, what precious, buried knowledge is held by Conall Canmore?
