The Throne of Dune and Leto of Dune
Two more book in the series were planned, but have both been put on indefinite hold.The Throne of Dune (previously announced as Irulan of Dune) would have concluded the story arc begun in The Winds of Dune, whereas Leto of Dune (possibly to be re-titled The Golden Path of Dune) was intended to illustrate events in Leto's reign following Children of Dune.
