I can't access the book review section, so I've put it here:

His Dark Materials Trilogy
Northern Lights, The Subtle Knife, The Amber Spyglass
By Philip Pullman

Northern Lights introduces Lyra, an orphan, who lives in a parallel universe in which science, theology and magic are entwined. Lyra’s search for a kidnapped friend uncovers a sinister plot involving stolen children and turns into a quest to understand a mysterious phenomenon called Dust. In The Subtle Knife she is joined on her journey by Will, a boy who possesses a knife that can cut windows between worlds. As Lyra learns the truth about her parents and her prophesied destiny, the two young people are caught up in a war against celestial powers that ranges across many worlds and leads to a thrilling conclusion in The Amber Spyglass.

The epic story Pullman tells is not only a spellbinding adventure featuring armoured polar bears, magical devices, witches and daemons, it is also an audacious and profound re-imagining of Milton’s Paradise Lost. An utterly entrancing blend of metaphysical speculation and bravura storytelling, HIS DARK MATERIALS is a monumental and enduring achievement.

Here’s an excerpt:
" He closed the book.

“And that was how sin came into the world,” he said, “sin and shame and death. It came the moment their dæmons became fixed.”

“But . . .” Lyra struggled to find the words she wanted: “but it en’t true, is it? Not true like chemistry or engineering, not that kind of true? There wasn’t really an Adam and Eve? The Cassington Scholar told me it was just a kind of fairy-tale.”

“The Cassington Scholarship is traditionally given to a free-thinker; it’s his function to challenge the faith of the Scholars. Naturally he’d say that. But think of Adam and Eve like an imaginary number, like the square root of minus one: you can never see any concrete proof that it exists, but if you include it in your equations, you can calculate all manner of things that couldn’t be imagined without it."

This is a book you need two copies of: one for the young mind you love and guide and one for yourself, so you can read it together and discuss it. It’s been pigeonholed as YA fiction, but Pullman had no target audience in mind. He wrote it for everyone.

Quote from Philip Pullman on His Dark Materials trilogy:
"I've been surprised by how little
criticism I've got. Harry Potter's been taking all the flak. I'm a great fan of
J.K. Rowling, but the people—mainly from America's Bible Belt—who complain that
Harry Potter promotes Satanism or witchcraft obviously haven't got enough in
their lives. Meanwhile, I've been flying under the radar, saying things that
are far more subversive than anything poor old Harry has said. My books are
about killing God."
