Add cover image and edition info

[Halvor (Raknes)]

I created this page yesterday, however I now realize I used the wrong cover image. Here's my scan of the correct image: https://www.goodreads.com/photo/user/...

edition: Fakkel

[Renske]

Done

I don't know what happened here.

This edition, https://www.goodreads.com/book/show/2..., remains hardcover.

This edition, https://www.goodreads.com/book/show/4..., should have "Fakkel" added to the 'edition' field.
