Linda M Priestly is also know as Linda Gruchy author of the gritty Death in Spiggs Wood. Even though that book has the word "wood" in the title, that's as close as it would get to this book that's full of flowers and weeds and vegetables and planting in an allotment.
Earth Magic is rather a magical tale of two young people who come across each other unexpectedly and help each other where they thought no one could help them. That sounds a bit soppy, but this story is not soppy at all. It's just lovely.
If you picked it up recently, bump it to the top of your pile. It's not a long story, which is good as once you start, you won't be able to put it down.
