How do I add a book I published, but didn't author, to a Giveaway?

[Remy]

My grandson has authored a book being sold on Amazon in paperback edition. He is too young to have his own account and I've been told by GoodReads that I can giveaway his book, noting I am the publisher. But how on earth do I add his book, when I'm not the author? I've tried everything and nothing works.
