Combine two versions of same book

[Simon]

Hello Librarians! What a wonderful service and what amazing people you must be!

Could you kindly combine these two books? They are the same book, but one seems to have perhaps been added by default via some unknown process.

PROPER VERSION OF BOOK (with reviews and author connections)
Sick Little Puppies

ADDITIONAL VERSION (with no proper info)
Sick Little Puppies: a horror short story collection

[Miriam]

Combined

The second copy is the Kindle edition (the 1st is an ebook edition) and was automatically imported by the Amazon bot.

Thank you!
