From New York Times bestselling author Patti Callahan comes an exquisite novel of Joy Davidman, the woman C. S. Lewis called “my whole world.” When poet and writer Joy Davidman began writing letters to C. S. Lewis—known as Jack—she was looking for spiritual answers, not love. Love, after all, wasn’t holding together her crumbling marriage. Everything about New Yorker Joy seemed ill-matched for an Oxford don and the beloved writer of Narnia, yet their minds bonded over their letters. Embarking on the adventure of her life, Joy traveled from America to England and back again, facing heartbreak and poverty, discovering friendship and faith, and against all odds, finding a love that even the threat of death couldn’t destroy.
