Blood Dawn

Four Russian submariners wash up on a Florida Beach in 1989, seemingly the survivors of a sunken vessel. The reason for their being in such close proximity to the American shoreline soon becomes evident, as an elderly couple overhears a conversation that leads them to believe there’s much more to the story than just a malfunction at sea. For over thirty years, the fabricated account of the soldiers’ tale remains a mystery.
Sean Mercer and his partner, Pat Vigil, are in Colorado conducting research at Rocky Flats when they inadvertently stumble upon a massive tunnel system lying beneath an old nuclear facility. The discovery leads to questions about an unsolved mystery from decades earlier, but finding the answers they seek could lead them down a path from which they might not return.
Upon ascertaining information about a Russian plot to smuggle a nuclear bomb into the United States, Mercer realizes there may be a link to the current conspiracy and the discovery about the past. The race is on to find the nuclear weapon and bring the madman responsible for the threat to justice, but will time run out before he and his partner can thwart the attempt to detonate a nuclear weapon on U.S. soil?
Blood Dawn is the third installment in the NESA Files series featuring Sean Mercer and the rest of the NESA team.
