First, the seller has not violated copyright law by selling you this book. Kirtsaeng v. John Wiley & Sons, Inc. provides the precedent. The Supreme Court ruled that the First Sale doctrine applies to "grey market" imports of books, so buying a book cheaply in another country and then shipping it to the USA is entirely legal, regardless of what the publisher would like.
The court wrote:
Putting section numbers to the side, we ask whether the “first sale” doctrine applies to protect a buyer or other lawful owner of a copy (of a copyrighted work) lawfully manufactured abroad. Can that buyer bring that copy into the United States (and sell it or give it away) without obtaining permission to do so from the copyright owner? Can, for example, someone who purchases, say at a used bookstore, a book printed abroad subsequently resell it without the copyright owner’s permission?
In our view, the answers to these questions are, yes.
Wikipedia also has an article on the case.
As for your recourse against the seller, this would seem to be very limited unless they specifically promised you the US edition, or the content is materially different between US and Indian editions. You don't say what kind of book this is. Textbooks typically have identical content. Fiction and other entertainment books generally have local idioms and terminology changed (e.g. "pavement" versus "sidewalk") but will otherwise be the same. You might be able to claim that this is a material difference, but its likely to be difficult.
