Brooklyn, the summer of 2015. The city is sweltering from another record-breaking heatwave, accompanied by biblical rains, and now a mysteriously glowing mushroom infestation is threatening the city. And as the mould spreads from house to house, frightened and bewildered New Yorkers wonder whether this plague on all their houses is an act of God ... Part horror story, part screwball comedy, and a novel about love found in the most unlikely of places.
