People of the Book (2008) by Geraldine Brooks

Synopsis: Follows a rare manuscript through centuries of exile and war, inspired by a true story. When it falls to Australian rare book expert Hanna Heath to conserve this priceless work, the tiny artifacts she discovers in its ancient binding—a butterfly wing fragment, wine stains, salt crystals, a white hair—only begin to unlock the book’s deep mysteries and unexpectedly plunges Hanna into the intrigues of fine art forgers and ultra-nationalist fanatics.
