I asked St Thomas' which was the best book to read as there were so many of them on the market. They suggested Talking about Lupus by Triona Holden. I found it quite helpful and I passed it around a few friends and it helped them to understand a little too. Plus it wasn't too scary either.
Triona herself is a Lupus patient so she understands too what it is like to be on this side of the fence (so to speak)!

My favourite book is New Hope for People with Lupus.
It is very readable unlike Dr Wallace's which is more of a reference book in my view although invaluable for detail.
New hope for people with lupus gives excellent practical advice on living with lupus - Mind -body connections, as well as excellent articles about alternatives and complementray therapies. The addresses are US but the advice about how to checking therapists and find them is applicable everywhere.
The facts and information about lupus is sound and there is no superficial & personal "I -have- found- the- cure" agenda being pushed. IMO,some of the books eg about diet are misleading and superficial containing frank inaccuracies and dubious speculations about the causes of and remedies for lupus.
Later: This book isn't listed on Amazon UK ! Look for it on Amazon USA.
