Author: Not sure.
Strange, I never really checked the site http://www.lawofattraction.com/ as I am quite a fan of the ideas of e.g. Abraham Hicks. And I just got there now with some affiliate link in one of the e-mails of the (inspirational?) sites I signed up for. And of course the link points to something that is being sold, but yes, I always admire the amount of effort that is being put in these type of ‘sales pages’.
So I’m not sure what the site is exactly about and what the exact story of Katherine Hurst. And well, she’s not in Wikipedia, so she’s not that famous, but if you have that domain you need to be somehow important. So I’ll check further and let you know more.
