I'm off to Borders, to pick up two more books. Trilogies are great, and as Susan pointed out, better read in order. The book I read was the last in this group, so some of the details that bothered me, that are woven in, are meant to link and pull the stories together. So in order to get the full picture, I'm going to read them all this week.
I believe this is the order, but please correct me if this is not the case...
Book one: Your Planet or Mine?
Book two: My Favorite Earthling.
Book three: How to lose an Extraterrestrial in 10 days.
Now the front of the book I have doesn't mention which it is, nor the inside cover. So upon picking it up, I assumed no particular order necessary. So thanks for the heads up, Susan. I'm sure the first two stories are just as fun and as sexy, and reading them will pull it all together.
