I'd worry too, Pegster. Agents always say they only take books they "love," but I wouldn't believe they really loved the book if they stepped in later. How would I know they would work with me on the NEXT book, which is what I would really be looking for at that point? My former agent didn't work with me on my second book, even though she loved my first one. Then again, it didn't sell, and maybe agents are more likely to love the later work of clients whose earlier work has sold.
