Fairies and Elementals for Beginners by Alexandra Chauran

I thought that this book would be about the different fairies and spirits that people have believed in over the centuries.  It does describe different types of 'elementals', but it's really a book about becoming close to them.

I liked it, but it's quite ethereal, and I haven't actually tried any of the suggestions.  The one about absinthe is a bit dangerous, because it's such an addictive drink!
