Which C.S. Lewis work was published posthumously after his wife’s death?

The C.S. Lewis work published posthumously after his wife’s death was A Grief Observed. Lewis’s wife, Joy Davidman, died of cancer in July 1960, and the book appeared in 1961 under the pseudonym N.W. Clerk.

The short work consists of reflections on bereavement, prayer, anger, doubt, and the struggle to reconcile suffering with belief in God. Its direct and unsettled tone differs from Lewis’s more systematic apologetic books, which is one reason readers sometimes mistake it for a conventional autobiography.

Lewis later acknowledged authorship, and the book is now normally published under his name. Joy and Lewis had married in a civil ceremony in 1956 and later received a Christian marriage ceremony in 1957. Lewis died in November 1963.
