Sleeping Giants

This story is told almost exclusively through interview tapes with the various characters over a few years. An ancient alien robot(mecha?) is discovered and resembled. The story deals with all of this information coming into the public light and the geopolitical situation that eventually develops from it. I'd be honest and say I wasn't hooked on the idea of continuing the series towards the middle of the book, but by the end, I have completely bought in and look forward to picking up the next installment.
