Ross Sidor's freshman entry in the special ops thriller genre, SCORPION, is an excellent read and a strong initial effort.
The plot focus around Avery, a former member of the 75th Ranger Regiment and a CIA green-badger who works high-level deniable operations. He is assigned to investigate the death of a CIA asset and the disappearance of the Dushanbe Station Chief. The novel quickly escalates into a counter-terror race-against-time plot that has been done time and again by authors such as the late Vince Flynn or Brad Thor.
What sets Sidor apart from those authors is his research. Everything is kept extremely grounded. Avery is a human character, albeit emotionally damaged. Contrary to some of the more critical reviews I've read, I didn't see him depicted as a "superhero." He gets injured, convalesces, and then pushes through the pain, which is common amongst special operations types.
The action is crisp, and the plot moves quickly from one point to another, allowing just enough time for some characterization and exposition before throwing Avery right back into the fire. Sidor is even better researched with IC terms than me, and I've been researching the IC for nearly two decades. It's refreshing to find those willing to do the research. It's also refreshingly absent of political bias, something often seen in a genre notorious for clumsily and ham-fistedly promoting conservative viewpoints.
That said, the book is not without imperfections.
The largest one is Sidor's tendency to summarize dialogue in prose when he could depict the conversation. It's not a massive imperfection, but it does merit mention.
After that, the biggest constructive criticism I could have offered would have been some closure between Avery and the supporting protagonist that he meets about halfway through the novel. Some of his weapons research is **technically** accurate but not practically accurate. There are also a few grammatical mistakes here and there.
None of those criticisms alter the fact that SCORPION makes for a thrilling page-turner. I definitely recommend it to fans of the genre. The first book is often the roughest, and Sidor's "rough" is an extremely entertaining read. He's only going to get even better as he continues to hone his craft. I look forward to reading more of his work.
