Query: Either poor quality or poor storage conditions

Bone by Bone appeared to be in good condition. However, when my husband started reading it (he was the first reader of a "new" book), the first 40% of the pages just fell out of the binding, some individually and some in chunks of pages. The book just came apart! Was it cheaply made? Being a Peter Matthiessen book, that's hard to believe. More likely, it had been stored somewhere exposed to fluctuations in heat/cold and humidity.
