All careful readers - and one must read Dune carefully or be hopelessly lost - must have noticed the discontinuities between the two earlier books and Children of Dune, ranging from minor details like the color of mourning (not yellow - GREEN) to large ones like Alia's sudden ability to access both male and female memories and a sharp reduction in her prescient abilities. And then there's the whole 'Golden Path' business.

So here is a totally AU version of COD that follows up the hint in Dune Messiah that Alia will bear a preborn child - or rather children.
