Query: Some of the BEST Sci Fi ever written

In his only outing into the science fiction genre, C.S. Lewis brings a mix of the fantasy of his Narnia series into a Jules Verne-style story of science fiction. In a universe where our planet is world under siege, Maleldil (God) reaches out to the "Silent Planet" in a story rich in plot, character, and philosphical complexity. A must read for every serious Christian who reads sci fi, and for everyone else trying to understand how science and Christianity can be reconiled in a way that is not only consistent but elegant.
