When searching for her father they come across a dangerous secret that threatens the fate of humanity; a disease that slowly turns those infected into living metal. Running from hunger, thirst, a mysterious metal lion, and the disease itself, Sarah must get the others to safety without getting caught by the creators of the disease that will do anything to cover their tracks.
The main thing I liked about this book was that the author researched the Kalahari to make her book as accurate as possible. I found it really cool that there were so many accurate facts that I never knew before. The story was also very fast paced.
The main thing I didn't like about the book was how they described the disease. The first sign of it was terrible itching which made me itch. I had to keep reminding myself that it wasn't real because I started to think I was getting infected by reading it!
Overall I would give this book 4 out of 5 stars.
