Joyce Nelson's new book, Sign Crimes/Road Kill (Between the Lines), is her long-awaited collection of thirty essays written over the last ten years. This is an important and eminently useful book: mediascape, mindscape, landscape: Nelson keeps her eye on everything Canadian, forever demonstrating for us the tools we need to think about those things ourselves. She's like Susan Sontag without the hare-brained stuff, or John Berger if he were to develop a sense of humour. Definite four-star material.
