Children of the Storm
falls entirely within the 7-month gap between Ch. 1-18 of Typhon Pact: Rough Beasts of Empire
(Feb-Mar '81) and Ch. 19-end of same (Oct '81-Feb '82). The rest of Typhon Pact
is set mostly in August to October '82, well after CotS. So strictly speaking, there's no overlap at all timewise, and none storywise either.
