From audible.com:

C. S. Lewis' dazzling allegory about Heaven and Hell - and the chasm fixed between them - is one of his most brilliantly imaginative tales, where we discover that the gates of Hell are locked from the inside.

In a dream, the narrator boards a bus on a drizzly afternoon in Hell and embarks on an incredible voyage to Heaven. Anyone in Hell is invited on board, and anyone may remain in Heaven if he or she so chooses. But do we really want to live in Heaven? This powerful, exquisitely written fantasy is one of C. S. Lewis's most enduring works of fiction and a profound meditation on good and evil and on what God really offers us.

The Chronicles of NARNIA

MERE CHRISTIANITY

First broadcast as informal radio "talks" and later published as three separate books.  The Case for Christianity, Christian Behaviour, and Beyond Personality are presented together in Mere Christianity.  In his remarkably  direct and accessible style, the renowned Christian apologist shows how the power of Christianity manifests itself - not in any single denomination but as "mere" Christianity, a total force.  For Lewis sets out to prove only that "in the center of each there is something, or a Someone, who against all divergencies of belief, all differences of temperament, all memories of mutual persecution, speaks with the same voice."

"Lewis is the ideal persuader for the half-convinced, for the good man who would like to be a Christian but finds his intellect getting in the way." - Anthony Burgess, The New York Times Book Review

"The point about reading C. S. Lewis is that he makes you sure, whatever you believe, that religion accepted or rejected means something extremely serious, demanding the entire energy of the mind." - Harpers

"If wit and wisdom, style and scholarship are requisites to passage through the pearly gates, Mr. Lewis will be among the angels." - The New Yorker

"A legacy of solid, genial Christianity." - Commonweal

C. S. Lewis was a professor at Cambridge and Oxford universities.  His other bestselling books include The Screwtape Letters, The Chronicles of Narnia, and Space Trilogy, all available from Collier Books.

Lewis's celebrated space world, Peralandra (the Planet Venus), has been invaded by the devil's agent in the shape of an English physicist, Dr. Watson.  Evil joins battle with good, represented by Ransom the philologist, as Peralandra and its Queen and Lady-Mother face the choice between ascending to perfection or following an older world to corruption.
