Wow, I've read and like loads of books but these are my all time favourites, I can't choose between these lot except that Harry Potter is and always will be my favourite!!
So here goes:
His Dark Materials - Northern Lights, The Subtle Knife and The Amber Spyglass
Lord of the Rings - The Fellowship of the Ring, The Two Towers, The Return of the King and The Hobbit
Artemis Fowl - The first one, The Artic Incident and The Eternity Code
The Edge Chronicles - Beyond the Deepwoods, Stormchaser, Midnight Over Sanctaphrax, The Curse of the Gloamglozer and The Last of the Sky Pirates
The Ender Series - Ender's Game
Sabriel Series - Sabriel
A Merlin Conspiracy
I've read others but these are the book that stand out, that I loved most.
I'd like to read the whole Ender Series and Sabriel Series and the rest of The Edge chronicles too so that's what I'm planning to read now, then there's a book called 'Eragon' I saw in the library and thought, 'Oooh!' and so I'll probably read that too, then I'll have to find something else to read while I wait for Harry Potter and The Half-Blood Prince to come out!
