Really nice set of covers..
BUT.....
Could you correct the double A on the second line of back text,
and the double TO in the sixth line, please. ....Not set in Kansas
Also maybe space the last bits of text downwards a bit
ie Who is the mysterious....., What are the Hallows.....,
They look a bit cramped (imo)
Also, you have left out the green box around Harry's portrait on the spine.
