Good reads?

I just got an email from "Margaret" who would "like to connect with you on Goodreads so we can share book recommendations.... Goodreads is a community for book lovers."

I don't think I know anyone named Margaret, and clearly she doesn't know me either. Books?? Reading?? Whoever head of such a thing?

The last book I read was about a blue kangaroo. Somehow I don't think she would be interested in getting a recommendation for that one.
