Hi Gwen,
When it comes to allocating books, the Book Club and First Impressions are treated as one big pool of books, so if you received a book through either program last month you'd be unlikely to receive another this month - as we allocate books based primarily on when someone last received one so the person who has not received a book for 4 months would usually get priority over the person who received one last month.
In general we're usually able to allocate books to people who have not received one for 3 months, sometimes we'll get a book that has relatively few requests compared to the number of copies available and then we might even allocate a book to someone two months in a row but that's unusual.
So, as you've probably surmised from this, the chances of you receiving a book this month when you got one last month are very low. But keep in mind you do not have to get a book from us to take part in the book club - if you can lay your hands on a copy from somewhere else (bookstore, library, friend) and read it you are more than welcome to join the conversation.
