Splinter

When Hector discovers his father has channelled the family fortune into a bizarre cult who await the imminent destruction of the Earth, he is wracked by feelings of betrayal and doubt. Things change, however, the night an asteroid plummets from space and shatters the planet, leaving Hector and the remnants of the human race struggling for survival on a splinter of the Earth.

And that's when the asteroid starts talking to him...

Splinter is inspired by the classic Jules Verne novel Hector Servadac, and features a lengthy afterword by the author.
