Act of War - Brad Thor

Act of War is novel 13 in the Scot Harvath series. China is getting greedy.

Topical as the latest news, America's laissez faire attitude toward immigration, and bureaucratic bumbling, could cost the country its very existence. Six Muslim students were interning at NASA because we must prove our country isn't Islamophobic. When these six engineering students overstayed their J-1 visas and disappeared, nobody noticed. That's the way the Chinese wanted it. Now Scot has to find them and stop a plot to destroy America. Very highly recommended.
