From my weekend's reading, this thriller, first in a series based around US SEAL and a threat to the US mainland.
From the Blurb:
The fate of America lies in the hands of one team of US SEALs. The US mainland is under threat as never before. Osama bin Laden is dead, and the world can relax. Or can they? Remaining leaders of Al-Qaeda want revenge, and they want it against the USA. When good fortune smiles on them and the opportunity presents itself to use stolen weapons of mass destruction, it's Game On!
