No spoilers. But this review encompasses the first 3 novels of the Delphi Group.
Book #1 was poorly edited, but in this book #2 the writing is much more refined and everything is just that much crisper and cleaner.
They are a nice mix of techno thriller, reality based sci-fi, and a detective story although it is a special operations man/team investigating. Sneeden has done very well to build a world in which the impossible just comes to life and it appears totally acceptable as possible. Solid science mixed with some pure fiction and you have a great thriller.
I read these a while ago, but still the story is fresh in my mind, which shows how much I enjoyed these Delphi Group novels (read the first 3 so far). It was obviously a first entry for the author and deserves better editing (might have just been the Kindle version wasn't edited properly). The plot moves along nicely. Characters are deeply described and developed. The world building and scene construction is top notch...I can picture most of the scenes described with very little effort, which is a sign a gifted writer.
The tie-in with Bible verses and history is a nice touch, for those who aren't easily offended by a writer assuming the Word of God is 100% truthful and accurate...yet he never makes any of those claims, he simply uses the Bible as another source for his characters to delve deeper into the mystery that has beset them. Sneeden ties-in everything with science that is rooted in real practical applications and studies going on currently all across the world, so they have a sort of mix between Phillip K. Dick, Michael Crichton, and Clive Cussler - yes, an odd mixture that Sneeden pulls off oh so well.
