I really enjoyed this (especially since it was hardcover and stayed open in my lap so I could knit and read at the same time... pure happiness, I tell you!). Parentheticals aside, I was unsure of the first person when I first started Deception, as Deadline and Dominion had been written in third person, but I quickly adapted.
A Christienian (Agathian?) plot twist, and a lot of good Christian depth.
While Deadline and Dominion dove, respectively, into abortion/premarital sex and racism/gang issues, Deception's focus is much more subtle. It focuses on the murder but just under the surface... the question: is God real? If He is, where am I going when I die? This is ironic, since the Heaven scenes, predominant in Deadline and almost as much so in Dominion, are quite muted in Deception.
I really loved how Randy Alcorn grew throughout the series as a writer. You don't really see that a lot, but you can in this series.
I would recommend!
