In his first story collection, Robert Charles Wilson, one of the most distinguished SF authors of his generation, weaves a tapestry of tales set in and around the city of Toronto - a haunted, numinous Toronto of past, present and future, buzzing with strangeness. In "The Fields of Abraham", one of three stories written especially for this collection, an impoverished immigrant boy is trained in strange disciplines by a bookseller who is more than he seems. In "The Perseids", winner of Canada's national SF award, love and amateur astronomy weave in and out of a terrifying tale of forced human evolution. In "The Observers", an awkward young Canadian girl who sees extra-human presences has an extraordinary encounter in 1950s California with Edwin Hubble. In "Plato's Mirror", a professional New Age charlatan has a genuine and terrible encounter with the extraordinary. And in the Hugo-nominated "Divide by Infinity", an aging Toronto book-lover finds himself becoming, literally, increasingly unlikely. Throughout are showcased Wilson's suppleness and storytelling strength: bravura ideas, scientific rigor and living, breathing human beings facing choices that matter in a universe stranger than we can imagine.
