La trilogie de la poussière Tome 2 : La communauté des esprits

Le jeune Will Parry, à la recherche de son père disparu depuis de longues années, est poursuivi par des hommes dont il sait peu de choses. Il traverse une brèche presque invisible, et pénètre dans une étrange cité, Cittàgazze, où des spectres mangeurs d'âmes rôdent dans les rues. Il y rencontre Lyra Parle-d'Or, qui a franchi le pont entre les mondes édifié par Lord Asriel. Elle aussi cherche à rejoindre son père. Ensemble, ils vont entamer un périlleux voyage à travers les dimensions, et découvrir un secret mortel : un objet d'une puissance extraordinaire et dévastatrice. Ils devront lutter contre les forces obscures du mal et, pour accomplir leur quête, pénétrer dans une mystérieuse tour, la Torre degli Angeli...

With The Golden Compass Philip Pullman garnered every accolade under the sun. Critics lobbed around such superlatives as "elegant," "awe-inspiring," "grand," and "glittering," and used "magnificent" with gay abandon. Each reader had a favorite chapter--or, more likely, several--from the opening tour de force to Lyra's close call at Bolvangar to the great armored-bear battle. And Pullman was no less profligate when it came to intellectual firepower or singular characters. The dThe Subtle Knife offers everything we could have wished for, and more. For a start, there's a young hero--from our world--who is a match for Lyra Silvertongue and whose destiny is every bit as shattering. Like Lyra, Will Parry has spent his childhood playing games. Unlike hers, though, his have been deadly serious. This 12-year-old long ago learned the art of invisibility: if he could erase himself, no one would discover his mother's increasing instability and separate them.As the novel opens, Will's enemies will do anything for information about his missing father, a soldier and Arctic explorer who has been very much airbrushed from the official picture. Now Will must get his mother into safe seclusion and make his way toward Oxford, which may hold the key to John Parry's disappearance. But en route and on the lam from both the police and his family's tormentors, he comes upon a cat with more than a mouse on her mind: "She reached out a paw to pat something in the air in front of her, something quite invisible to Will." What seems to him a patch of everyday Oxford conceals far more: "The cat stepped forward and vanished." Will, too, scrambles through and into another oddly deserted landscape--one in which children rule and adults (and felines) are very much at risk. Here in this deathly silent city by the sea, he will soon have a dustup with a fierce, flinty little girl: "Her expression was a mixture of the very young--when she first tasted the cola--and a kind of deep, sad wariness." Soon Will and Lyra (and, of course, her dAs Pullman moves between his young warriors and the witch Serafina Pekkala, the magnetic, ever-manipulative Mrs. Coulter, and Lee Scoresby and his hare dThroughout, Pullman is in absolute control of his several worlds, his plot and pace equal to his inspiration. Any number of astonishing scenes--small- and large-scale--will have readers on edge, and many are cause for tears. "You think things have to be possible," Will demands. "Things have to be true!" It is Philip Pullman's gift to turn what quotidian minds would term the impossible into a reality that is both heartbreaking and beautiful. --Kerry Fried

Ayant franchi le pont entre les mondes édifié par Lord Asriel, son père, l'intrépide Lyra se retrouve dans la cité de Cittàgazze, la ville au-delà de l'aurore, où des spectres mangeurs d'âmes rôdent dans les rues, où les lointains battements d'ailes des anges résonnent au-dessus d'une mystérieuse tour.
