This is the first book I am going to talk about.  Now, I know this is not to everyone's tastes but remember I will also consider reading books you suggest.  This book is written by Stephenie Meyer, who also wrote the Twilight series.  I will probably rate those ones too.  Personally I thought this one was better than Twilight but that is my personal opinion.  This book is about a group of aliens who takes over the human race because they need hosts to survive.  Hence the name of the book.  We follow a specific alien called Wanderer and her struggles with her body.  She is put into the body of Melanie Stryder who apparently is not going to give up her body easily.  Wanderer remembers and feels things that Melanie does and sometimes that creates conflict for her.  She also hears Melanie in her head as Melanie's will becomes stronger.  This leads Wanderer into a whole adventure of discovering what they are doing to humans and how it ultimately effects her.  I personally loved this book.  I couldn't put it down and it was very well written.  The only thing I would say against it is if you are not an avid reader (like me) it can be kind of long.  But its worth the wonderfulness of the story and I'm glad it lasted as long as it did because it was hours of fun for me.  Plus, I am a die hard romantic so this book was perfect for my tastes and anyone else who enjoys a good, steamy romance.  I highly enjoyed this book and I hope you feel that I was accurate in my rating of it. Out of ten stars I would give it an eight and a half.
