I just finished Adiamante by L.E. Modesitt, and I find it strangely relevant, especially since I read it right after Haze. I love the idea of making the power you gain with technology cost you personally, including the hidden costs — even if you use it for public good, you still have to pay the costs. And you pay them in your personal time, by doing work — something that can't be traded, taxed, pensioned or outsourced. That means you still can do big things, but it costs you.
