This is a boxed set all seven Harry Potter titles - "Harry Potter and the Philosopher's Stone", "Harry Potter and the Chamber of Secrets", "Harry Potter and the Prisoner of Azkaban", "Harry Potter and the Goblet of Fire", "Harry Potter and the Order of the Phoenix", "Harry Potter and the Half-Blood Prince" and "Harry Potter and the Deathly Hallows".
Not sure what the 'adult' refers to. From the reviews on Amazon it means that the books are better bound with a different image to the kid's versions. Hopefully not an alternative story line with Harry getting several schoolgirls pregnant and being expelled........
I found this set after looking for the books for my daughter. Delivery is 28 days, but the next best price I could find is over £40 (Amazon is £47.99) so it might make a decent present for Christmas.
4% Quidco would bring these down to £28.80.
