At the end of The Northern Lights, Lyra Silvertongue watched in fear and fascination as her father, Lord Asriel, created a bridge between worlds. Lyra and her daemon Pantalaimon are now lost in an alternate universe where they meet Will Parry, a fugitive from a third universe. Will has found a small window between Cittagazze--where children roam unchecked, but invisible Specters suck the spirit out of adults--and his Oxford, which, with its Burger Kings and cars, is frighteningly different from the Oxford Lyra knows. Will's father, an explorer, disappeared years ago, but some odd characters have started asking questions about him. Will has managed to accidentally kill one of them and is wanted by the police. Armed with the Subtle Knife, a tool that cuts any material (including that which separates universes) and Lyra's alethiometer, the children set out to find John Parry, with adults of various stripes in desperate pursuit.

Lyra's finest qualities are her courage and her quick mind. She finds she must use them constantly--not to put too fine a point on it, she must lie and steal to keep herself and Will out of danger. However, she must also know when to tell the truth and when to trust. She does not yet know--though her friends the witches do, and so does the reader--what a huge part she will have in the upcoming battle between Good and Evil. (Age 9 and over) - -Amazon.com

Like Northern Lights, I found this a bit of a slow starter, but once it gets going you suddenly realise the sheer breadth and scope of the trilogy's vision - huge!

A lot more adult in tone than Northern Lights, which made for a better reading experience for me. This book also starts to deal with some very adult themes, such as death, religion and authority.
