About the models,
If you buy the book expecting to get airbrushed ultra skinny fashion models, you might be disappointed. But, if you want naturally beautiful models photographed in clear lighting so you can see every bit of them, then this book is great. And there's a nice range, from Susan who is slim and athletic and has a classic Greek-sculpture face to someone like Jen with her amazing natural figure and more modern look.
The previews above give a good idea of the range of models but it's kind of hard to see how beautiful they are. And a couple of my favorites, Jessica and Jennifer (who have pin-up style figures) are missing.
So, if you want supermodels, go buy a fashion magazine, or if you want erotic models airbrushed to look like plastic, go buy a men's magazine, but if you're looking for attractive naturally beautiful models, this is the book to get.
The poses are good too.
