I had read another Goodwin/Pierce project book and so I knew what I was in for. So, I took it as it came took me, including some surprises in the evolution of the story. This box set of four books kept me engaged at least 95% of the listening time – not many dull moments. Further, it not-so-subliminally instructs, similar to Crichton’s edifying stories most of us really enjoyed. If one has an open mind, I could easily recommend this seriesset of 4 books.
