While studying at Oxford, Sheldon and Davy develop a friendship with C.S. Lewis, under whose influence and with much intellectual scrutiny they accept the Christian doctrine. As their devotion to God intensifies, Sheldon realizes that he is no longer Davy's primary love--God is. Within this discovery begins a brewing jealousy.
Shortly after, Davy acquires a fatal illness. After her death Sheldon embarks on an intense experience of grief, "to find the meaning of it, taste the whole of it ... to learn from sorrow whatever it had to teach." Through painstaking reveries, he comes to discover the meaning of "a mercy as severe as death, a severity as merciful as love." He learns that her death "had these results: It brought me as nothing else could do to know and end my jealously of God. It saved her faith from assault. ...And it saved our love from perishing."
Replete with 18 letters from C.S. Lewis, A Severe Mercy addresses some of the universal questions that surround faith--the existence of God and the reasons behind tragedy. --Jacque Holthusen
