If outdoors survival is your thing, then you will not be disappointed in this fifth John Milton book. Personally, The Sword of God (Milton #5) was not my cup of tea, especially as John Milton, who's been wandering (yes, on foot), in the Upper Peninsula, MI, and has, by happenstance, come across a group of white supremacists/militants who plan to commit acts of terror against their government in the name of God. Admittedly, for me that religious babbling as an excuse for violence is so not interesting, so not understandable, that I skipped those parts, to be honest. As for John trying to make it out alive being tracked by those dangerous lunatics, there's no doubt I root for Milton, but there was no element of surprise, no originality to this entire plot. We know what John Milton is capable of. So, yes, this story was a bit of a let-down. Milton's brief (sexual) encounter with Ellie Flowers, FBI Agent, was also redundant and misplaced, in my opinion. Anything but that would have been more believable.
No, not the best Milton.
