Lol potato goddess what was her name?
I don't know of any reliable books but I have seen a few. Study the mythology, in my opionion it will help you understand faeries/fae better. I do know a bit of stuff, but not how to work with/practice fae Wicca. I know they enjoy sweets and saffron. They also hate greed, so if you have a garden or eat outside, put some food asside. Faeries also aren't happy sweet creatures, they can be vengeful. Plant a garden for them, sweet smelling flowers that attract butterlfies and hummingbirds are best. I do know of people who leave the area alone and never enter it since it doesn't belong to them once it's been given to the fae [or other spiritual being.] Also read once faerie cakes [or whatever offering] shouldn't have any toothpick holes [when you check a cake most stick a toothpick in it] apparently certain faeries get highly insulted [which I can't remember, I read it years ago and it was about world mythology]
Just a few ideas, good luck to you.
