An incandescent novel of love, obsession, and the secrets that take root in the human heart, by the author of The Copper Beech and Circle Of Friends. Lough Glass is at the heart and soul of the namesake town clinging to its shore. They say that if you go out on St. Agnes' Eve and look into the lake at sunset you can see your future. But beneath its serene surface, the lake harbors secrets as dark and unfathomable as the beautiful woman who night after night walks beside its waters. Lough Glass is home to Kit McMahon, in a way it will never be to her lovely mother, Helen, who does not fit in with the ways of the people of Lough Glass, and who found an unlikely mate in the genial pharmacist Martin McMahon. Kit adores her mother, but can't escape the picture of her, alone at the kitchen table, tears streaming down her face... or walking alone by the glass lake. Then one terrible night Martin's boat is found drifting upside down in the lake. The night Helen is lost. The night Kit discovers a letter on Martin's pillow and burns it, unopened, in the grate. The night everything changes forever.
