Cold Evidence by Rachel Grant

Rating: ⭐⭐⭐⭐⭐

What starts out as a simple accident turns into a terrorist plan for vengeance on the United States. An Ex-Seal and a Navy archaeologist take on the diving to find why a submarine that sunk back in 1962 is on another country's radar. These two are reunited after a major fall-out 8 years ago, but in this story the Pacific Northwest is about to get hotter than these two. This story is intriguing and just when you think the story is done, the real action begins. Page-turning from the first dive to the last, I was hanging in mid-air by the time this story reached it's conclusion.
