A Fragile Hope — Cynthia Ruchti

Josiah Chamberlain's life's work revolves around repairing other people's marriages. When his own is threatened by his wife's unexplained distance, and then threatened further when she's unexpectedly plunged into an unending fog, Josiah finds his expertise, quick wit and clever quips are no match for a relationship that is clearly broken.

Feeling betrayed, confused, and ill-equipped for a crisis this crippling, he reexamines everything he knows about the fragility of hope and the strength of his faith and love. Love seems to have failed him. Will what's left of his faith fail him, too? Or will it be the one thing that holds him together and sears through the impenetrable wall that separates them?
