I am trying savour reading the last of the Harry Potter books while trying to read it quickly so as not have it 'spoiled' by some overheard comment or cruel composer of newspaper headlines.

And I am being thrwarted.

I am at page 256 (this edition) and in mid-sentence a new chapter begins. I glance at the page numbering to see that what should be 257 is now 513 page mark. Carefully scanning forward, the normal flow of narrative does begin again... but at page 289.

I did a quick search on the web for Harry Potter and missing pages and came up with none. Is it possible that this error is a one-off?

If so, I'm hoping its of some value to someone else because I am now off to buy another Harry Potter and the Deathly Hallows.
