Cat Cross Their Graves
The tenth book in the Joe Grey series, 2005
I do not know that I ever saw anything more terrible than the struggle of that… Ghost against joy. For he had almost been overcome. Somewhere, incalculable ages ago, there must have been gleams of humour and reason in him… But [now] the light that reached him, reached him against his will… he would not accept it.
– C. S. Lewis, The Great Divorce
