Lyra finds herself in a shimmering, haunted otherworld – Cittàgazze, where soul-eating Spectres stalk the streets and wingbeats of distant angels sound against the sky. But she is not without allies: twelve-year-old Will Parry, fleeing for his life after taking another's, has also stumbled into this strange new realm. On a perilous journey from world to world, Lyra and Will uncover a deadly secret: an object of extraordinary and devastating power. And with every step, they move closer to an even greater threat – and the shattering truth of their own destiny.
