Alarmed that Canada Post keeps losing money, Ariadne Jensen, a woman in her fifties, pitches the CEO with a scheme to save the corporation: she will get people to start writing and mailing letters again. As an inspiration to others, Ariadne writes bundles of letters for all to see; some are historical fiction, while others are drawn from her own correspondence. Each letter itself tells a story, while together they form a bigger story--about Ariadne, her determination to set wrongs right, her sly humour, and her loyalty to her best friend Leo, a gay man in his early twenties--that leaves the reader of At This Juncture informed, educated and, most importantly, entertained.
