[done] merging audiobook into main book entry

[Fallenpenguin]

Hi,
this is the main book entry that is also attributed to the correct series: https://www.goodreads.com/book/show/2...

For some reason the audiobook has its own entry and should be merged into the above entry: https://www.goodreads.com/book/show/2...

Thank you very much!
