" OK - well, I'm happy that I read the trilogy, but, to be honest the first book could have been three or four chapters longer and included everything that was really interesting from books two and three. The final chapter of Vortex was pretty cool - I love the ideas in there. It's really too bad that the entire book (or perhaps this entire book and Axis as well) didn't focus on this and expand on the ideas (and explore the Ring of Worlds also). I never felt that I had all that much invested in the characters in the latter two books. Still, nanobots - am I right? "
