question:
I love this novel and ordered it for my mom. The price was high enough [exorbitant] for a paperbound book that I thought that the novel would be complete. The product description says NOTHING about it being one volume of a complex work. It is one volume, not the complete work, I was embarrassed to discover from my mom. Where is the rest of the work? NOT AVAILABLE? Available for an additional [exorbitant] sum? If it had been an order for myself, I would return, but my mom is 3,000 miles away and I do not want to add insult to injury by asking her to pack and return ship, so injustice has been rewarded.
answer:

Negative
