The Invisible Heart

I am reading The Invisible Heart by Russell Roberts for my economics course. It says on the front cover that it is an economic romance. I started reading it last night and got half-way through the book. So far, I think it is probably a romance novel about an economics teacher and an english teacher. There is also another story (that I'm sure will tie in later) about a pharmaceutical (sp?) corporation relocating to Mexico. That side-story is obviously so deeply about economics. Russel Roberts is an excellent author. Anyone that can keep MY attention has to be because I do not particularly like to read. I can't wait to get back to this book and see how the two stories blend together.
