This book has a even more epic feel then the last of the series. I liked the idea of pitting two sisters, Noor and Chanai, competitors to the throne, against one another, in a planetary take down. This is what this book is about. Noor inherits the earth from her mother Sidus. And Chanai steals the royal Mars fleet from her sister, freeing 100,000 captives doomed to die.

Good stuff. But here's where it gets interesting. How exactly do you make Mars livable? So many books, from the Martian Chronicles to  The Martian imagine how this could be done. I imagine a hundred year journey just to make it from underground barracks to clean air and water on the surface. 

I too, want to travel to Mars one day, and know, with the collective wisdom of all of us, it is possible.
