Query: Poorly bound books

As other reviews have stated, the stories and art work are exactly what you'd expect and my 6 yr old son and I eagerly devoured the two volumes we had purchased. The second night we read them, however, the pages started falling out. By day three both books were utterly destroyed. Very, very poorly bound books. I would expect the returns on these titles to be extraordinary.
