The Apocalypse Trilogy

If not for the apocalypse, I would have lived an ordinary life. But because of it, I became the luckiest person in the world.

What do I mean by lucky? Three things:

First, I was the first mutant confirmed to be an immortal.

Second, because I belong to the lowest rung of society, I am completely safe and don't have to be monitored around the clock.

Third, I am infertile.

I seem to have gone off on a tangent. As the chronicler of the apocalypse, I should talk about something related to it. Well, the apocalypse really does come in three stages: first, the Himalayan Disease; second, the Land Without Oxygen; third, the Solar System's Lament.
