Warcross

First of all this is not a complete story, and the story is about to continue in another book or series of books and this is not mentioned anywhere in the paperback (no Warcross #1 note or ...). Additionally the story has its faults: the main antagonist which seems to be some kind of terrorist or anarchist trying to demolish everything, has other intentions revealed further. He could explain himself when he was trying to pursue the main protagonist to stop her work or even work with him and does not do so. Why?
In another perspective the book is an easy read, an enjoyable one and a amusing peace of work (regarding the image it creates of a widely used augmented reality system and virtual reality system). Although I may be too cruel here, I guess I did not gain something considerably valuable reading it (other than getting a clue on what Young Adult genre looks like) and if I knew about the kind of book I am choosing to read prior I guess I preferred another book to fill my time with it.
After all, I guess if I could get my hands on the sequel, I would read it to see how unanswered questions of this book find their answers there.
