The Shan, immortal alien shapechangers, who could offer mankind both the freedom of the starways and an eternal lifetime to explore the universe. The Phoenix Group, shipwrecked Shan, separated from the last remnants of their race, working secretely on Earth to bring human technology to the level that would enable them to repair their own spaceship and rejoin their people on the last Shan citadel world of Haven.
But time was running out for Shan and human alike, for there was another race of space-going aliens loose in the galaxy, a race of destroyers on a deadly hunt for the Shan. And even if humans and Shan allied against this foe, it might already be too late for either race to escape the wrath of these conquerors from the stars!
This is how Species should've portrayed its alien/human hybrid idea. Also thought provoking ideas about nuclear weapons and their purpose, which makes sense considering this was written in 1987, during the cold war. I'd say worth the read, but I'm still not sure how I feel about the ending. Not a bad ending, just...I'm not sure about it yet. Don't let that discourage you, you may thing differently.
This was written by the father of a co-worker. I enjoyed it but am a little bummed that there won't be a follow-up by the original author (though maybe by his son).
