The Secret Commonwealth: The Book of Dust Volume Two: From the world of Philip Pullmans His Dark Materials - now a major BBC series (Uncorrected proof)

It is twenty years since the events of La Belle Sauvage: The Book of Dust Volume One unfolded and saw the baby Lyra Belacqua begin her life-changing journey.

It is seven years since readers left Lyra and the love of her young life, Will Parry, on a park bench in Oxford's Botanic Gardens at the end of the ground-breaking, bestselling His Dark Materials sequence.

Now, in The Secret Commonwealth, we meet Lyra Silvertongue. And she is no longer a child . . .

The second volume of Sir Philip Pullman's The Book of Dust sees Lyra, now twenty years old, and her daemon Pantalaimon, forced to navigate their relationship in a way they could never have imagined, and drawn into the complex and dangerous factions of a world that they had no idea existed.

Pulled along on his own journey too is Malcolm; once a boy with a boat and a mission to save a baby from the flood, now a man with a strong sense of duty and a desire to do what is right.

Theirs is a world at once familiar and extraordinary, and they must travel far beyond the edges of Oxford, across Europe and into Asia, in search for what is lost - a city haunted by daemons, a secret at the heart of a desert, and the mystery of the elusive Dust.
