AB Philip Pullman The Subtle Knife

The universe has broken wide, and Lyra's friend lies dead. Desperate
for answers and set on revenge, Lyra bursts into a new world in pursuit
of his killer. Instead, she finds Will, just twelve years old and already
a murderer himself. He's on a quest as fierce as Lyra's, and together
they strike out into this sunlit otherworld.

On this journey marked by danger, Will and Lyra forge ahead. But with
every step and each new horror, they move closer to the greatest threat
of all and the shattering truth of their own destiny.

In this stunning sequel to The Golden Compas, Philip Pullman continues
His Dark Materials trilogy and confirms it as an undoubted and enduring
classic.
