India Post — Package not delivered, very late

My package with the tracking number, UM[protected]US, containing a book, shipped from the U.S. hasn't been delivered yet and it has been more than month. The last update was, " Departed. Your item departed a transfer airport in INDIRA GANDHI INTL, DELHI, INDIA on April 23, 2022 at 9:45 pm. The item is currently in transit to the destination." and it has been almost a month since then. I really need it since it's a collectible and another one with the same specifications doesn't exist.
My address is-Neelam Sharma
