The Last Sydney Carton

It's hard to make time for romance when the world is about to end.
Lewis McKnight just wants to make it out of high school, but his approaching graduation loses all significance when an impending Cataclysm approaches. It's the end of the world, but he doesn't feel fine.
All he wants to do is track down his ex and apologize, and when he wins a lottery ticket to the newly-constructed Haven, he finally gets his chance. But with time running out, his moment of truth might be spoiled by the end of all things.
