This is a story where the end almost defend the means. It’s a good idea, but the protagonist is a “Wesley Sue” that is better than anyone and always is right. It’s like a Sherlock Holms whiteout Watson.
The motivation of the bad guy is never truly explained. There is a reason for what they are doing, but the time and effort they put in to their scream just doesn’t add up. However, the book is the first in a series, so maybe that will be explained.
In addition the women are embarrasly sexy and the protagonist seduces one in his crew by sexual horsemint. And of course the drunk is Scottish. All of this drags down an interesting plot in interesting locations.
