Q: Who (or what) is The Guide? What happened to the Mandarins? What becomes of Josh’s mother? Who will rule Mars? How can you end the book with Earth in, er, the state you leave it in?
A: That last question definitely flirts with spoilerdom.
Patriots is only the first of a planned series. Only some of the questions it raises can get answered in the first installment, but enough do get resolved (I believe) to make the book satisfying in itself.
