The Fleet of Stars

Poul Anderson marks the 50th year of his science fiction writing career with the conclusion of his Harvest of Stars series (Boat of a Million Years, Harvest of Stars, The Stars are Also Fire, Harvest the Fire). While the writing is leisurely, the action bounces between the solar system and the stars as Anson Guthrie returns to action once again (or at least his downloaded consciousness does). It seems the artificial intelligence that half support and more than half control the Terran system are hiding something from humanity, and Guthrie is determined to find out what that is.
