I love Google Alerts. This one came in yesterday:
A lovely new (or new to me) review for Let's Go!
Are you an author? Ever tried out the Google Alert thing? It's a wonderful way to find out when something about your book is posted online, or at least when Google finds out about it.
When you set up the alert, make the keyword(s) your book title. So long as you're not offended when you see it auctioned on ebay, it's fascinating to see where it pops up!
