Tower of the Hand

Nearly 170 years before the events of the series, there was a conflict known as the "Dance of the Dragons" during which Aegon II Targaryen and Rhaenyra Targaryen fought over the Iron Throne. Does the title of the next book, A Dance with Dragons, imply a brewing civil war between Targaryens? Of course, we only know of one surviving Targaryen to date, so it seems more likely that Daenerys and her dragons will be invading the Seven Kingdoms. Or perhaps Dany will see Stannis's wisdom and ally herself with Westeros against the Others. Then again, the latest book saw many factions planning to win Dany's hand in marriage, so the "dance" may mean her courtship. To what do you think the title A Dance with Dragons most likely refers?
