His Dark Materials: The Subtle Knife

The Subtle Knife is the second part of the trilogy that began with The Golden Compass. That first book was set in a world like ours, but different. This book begins in our own world.

Kyra journeys to the shimmering, haunted otherworld called Cittágazze, where she meets Will Parry. Together they travel from world to world and discover an object of extraordinary power, and uncover the truth of their own destiny.
