A Pure Clear Light — Madeleine St. John

At once poignant and humorous, this deliciously devised novel lights on the marriage of Flora and Simon Beaufort just at the moment it goes haplessly awry -- the moment that Simon succumbs to the temptation of his cool, blond accountant and Flora heeds the cry of her reawakened faith. Ultimately, though, neither of them can escape the revelation that lies beyond excuses and candor, at the heart of a phenomenon called love.
