Eleven Numbers by Lee Child

This was exactly as basic as I expect popular best-selling fiction to me. And sure enough, it has a ton of great ratings and reviews.
The general audience doesn't seem to need or even particularly want to be intellectually challenged.
Child understands it and leans into simple in both concept and language. So here you have a simple story of some math-themed espionage.
I wonder if every character in Child's fiction has a sort of built-in Reacher levels of stoic heroism or if that's just all he can write. Because here you have a mild-mannered mathematician who suddenly turns into a superspy able to withstand a brutal political prison system. Um, yeah, sure.
And here are some more examples of basic, this time when it comes to the actual writing / editing:
a commander-in-chief who "radiated charm and charisma" - um, someone grab a dictionary and saying something was a mirror image but otherwise the same - yeah, that's what it means, again, a dictionary wouldn't go amiss.
At any rate, this was a quick mindless read that despite its various shortcomings will surely continue to dazzle the undemanding. Thanks Netgalley.
