Heinlein, award-winning maestro of the SF world, surpasses himself in this, his most powerful novel. And there is time enough indeed for love, as Lazerus Long's lifespan covers 23 centuries. He is "the senior" - the oldest man alive in the Galactic Year 2053 - the man who is forever young. And Heinlein traces his fantastic life - or lives - through many marvellous identities: from Lazarus Long who lead the first great exodus from Earth, to Aaron Sheffield, interstellar star-ship captain, through to Ted Bronson, the time-traveller, catapulted through time back to Earth in 1916.
