Diane Engelhardt lives on Salt Spring Island and in Victoria and has published under the name of D. S. Hartley a creative non-fiction book titled All Our Friends: Simple Rewards of Simple Living (Trafford Publishing).

All Our Friends explores a life of voluntary simplicity on Mayne Island, and relates the experiences we had with a family of raccoons who turned the yard into a garden stage. This story should appeal to wildlife enthusiasts, nature lovers, and international readers who associate British Columbia with nature and wildlife, and who can appreciate the challenges of a modest island lifestyle.
