Duplicate, perhaps?

[Angela]

This book, Candy Apple #3: Miss Popularity, appears to be a duplicate. The others in the Candy Apple series, that are also in the Miss Popularity series, are listed differently.

Here, Miss Popularity appears to be a more complete version.

The first one you linked does not have any ISBN listed, so I'm not sure if it's a separate edition, but in any case, I merged the two (as well as a Spanish edition of the same book).
