His Dark Materials trilogy by Philip Pullman. Fantasy. Okay - so no surprises here! But these books are just fabulous - definitely challenging for a struggling reader and at the upper end of the 7-13 age group - I would say a confident reader aged from 10 to 100!
Handwritten notes by J.K. Rowling in a first edition of 'Harry Potter and the Philosopher's Stone' auctioned off to support a literary charity "Perhaps Hufflepuff would have the respect it deserves from fans if I'd stayed with my original idea of a bear to represent it." Even JK Rowling knows Hufflepuff deserves more respect!!!
