Cade and Brook are brother and sister whose parents work for the CIA and FBI. Despite this, they live pretty normal lives until they overhear their parents talking about a mole leaking information. From there, things go downhill as one by one their parents go missing. Cade and Brook are the only ones with any hope at keeping their parents alive and recovering a top secret piece of technology with the power to start nuclear war. They're up against terrorists, on the run, and only have ten days to fix everything.
I really liked the book. It was interesting at the beginning but the real action didn't start until after the first few chapters. I think that It is a good book. There are still mysteries left at the end which make you expect a sequel. Overall I liked the book, but it was not particularly amazing in any way. There were parts that I liked and even though I still had questions at the end, there was enough information to keep me satisfied. I would reccomend this book to younger children, because it lacks real action and crisis situations that older-age group books might have.
