Vegetable book that takes account of shade

Permanent Publications are bringing out "Edible Perennial Gardening" by Anni Kelsy in n November, which seems ages to wait.

She has been experimenting with perennial vegetables, including growing some annual vegetables as perennial vegetables. She has undertaken many experiments, including most importantly for me personally, and for those trying to live a green and country living in an urban environment, growing these vegetables in SHADE!

Looking forward to reading this book.
