Hi,
Essential Lenormand by Rana George : a very good book for beginners in my opinion. Easy to follow and well written. I've read it back to back in a couple of days, LOVED IT !!
The Complete Lenormand oracle Handbook by Caitlin Matthews. A bit hard to get into, very complex and detailed but once you've get the gist it's an excellent resource for the reader who wants to explore the Lenormand's world in deph.
There is also Andy's book "Lenormand thirty six cards" but I can't coment on it as I've just purchased it but not read it yet.
