"It would be difficult to overstate the wonder I felt while reading this novel. It's among the most beautiful books I've ever read about longing--for beauty, for sex, for God, for a coherent life."--Garth Greenwell, author of What Belongs to You Maggie is entirely devoted to her husband Thomas, their two beautiful children, and to God--until what begins as a platonic intellectual and spiritual exchange between writer Maggie and poet James transforms into an erotically-charged bond that challenges Maggie's sense of loyalty and morality, drawing her deeper into the darkness of desire. A daring debut novel of obsession, lust, and salvation by the highly lauded author of the story collection, I Want To Show You More, Fire Sermon is a tour de force that charts with bold intimacy and immersive sensuality the life of a married woman in the grip of a magnetic affair.
