This book is a companion to Whirlwind. It takes a part of the story and develops it further. There is a certain amount of crossover with the previous book but it does help to round out the story.
It follows the love story of Erikki and his Iranian wife Azadeh as they try to cope with the turmoil of civil war racked Iran and her father, the Khan, and their attempts to escape to freedom.
We also have part of the Whirlwind story to help carry it through.
This is a good story with tension and dramatic events. They are pushed into tight situations and plenty of action. The appearance of the mysterious Captain Ross brings more acion and tension to both the story and the lives of the two lovers.
However, as good as it is, you get the feeling that this is what his editor told him too leave out of the original. Then after its success they decided to release this as a spin-off.
Its worth reading after Whirlwind but only if you want to know more of what happened to the two lovers.
