I genuinely like the design of this cover, but on the basis that covers of books tend to feature the main character (and I applaud the way the artwork doesn’t show the man full face, meaning that you won’t have your mental image of the character barged aside), I guess that this cover shows Reilly’s recurring character Jack West Jr.

But, um, doesn’t he have a bionic arm made of titanium steel? It doesn’t look that way from the cover picture.

Unless, of course, he got his arm back in the previous book, but I haven’t read that one yet.
