1st book in the WMD Files sub-series.
"When Navy SEAL Lieutenant Brendan McHugh captures an Iranian diplomat on an anti-insurgency raid, it just feels all wrong. The rules of engagement say he must let the diplomat go, but that doesn't stop McHugh from asking questions. With an FBI linguist and a CIA analyst on his team, he chases clues across the globe to uncover a terrifying plot. Iraqi weapons of mass destruction are real and in the hands of an Iranian splinter group. The threat to the United States heartland is bigger--and closer to home--than anyone dreamed possible."
