This is book 1 of the "Trigon Disunity" series.
This note contains spoilers for the book.
The first of the series containing Enigma. This takes us through a somewhat interesting but pretty irrelevant social catastrophe involving the end of science up through first contact, and the startling discovery that the aliens we have contacted are human. Apparently there was a prior civilization on earth which planted colonies.
