Worth a read & makes some very interesting points

I'm now about 3/4 of the way through the book. Its fun but highly improbable - & tbh it does sail a bit close to the wind as far as 'infringing' goes.... But I've enjoyed it as a guilty pleasure & frankly there's no way it could harm Tolkien's work & should have just been ignored. The Estate (or their lawyers) have been really dumb here, because even if they had a case technically, they look petty & bullying.
Still - the piece linked to offers a very good case for the defence.
