Intervention (1987) is a standalone novel by Julian May that connects her two major science fiction series. The book covers the period when psychic powers first emerge on Earth and the initial contact between humanity and the alien Galactic Milieu.
The novel works as both a standalone story and as essential reading for fans moving from the Pliocene Exile saga to the Galactic Milieu Trilogy. It fills in the historical gap between the two series and introduces key families whose descendants appear in the later books.
