Not surprisingly, with Reilly at the helm, this was a cracking good read. Tons of action, some great lateral thinking by Scarecrow against a very unexpected foe. I now remember why I re-read a Matthew Reilly book when I need something unusual with the tension and suspense ratcheted up to extreme levels. Better than a gym visit for a cardio workout and much more satisfying. I'm off to re-read Seven Ancient Wonders. I need more exercise!
