"The Master of Electricity: Silent Currents" is pitched and submitted as part of the Urban Fantasy core, fitted to a genre -- and an interpretation of that genre -- hat has some very specific requirements and expectations. This story pretty much nails all of them.
And I know, to some people, some of this would feel like a negative: Master of Electricity has every beat that's endemic to its genre home turf. Its heroes, its antagonist, and everything they go through hits the beats in time with what you would expect. But it's also in time with what you'd hope for. Something I've often said is that there are an infinite number of wrong ways to go with a story, and a finite number of correct ones. In that light, I mean it as praise when I say that Master of Electricity hits every beat. It's performing, to an extent, a tried and true piece, but it performs that piece very well.
Overall, I feel like the second half was stronger than the first. It's only after we've gone through a few more episodic skirmishes with the story's antagonist that we really get a feel for our main characters, and the bond between them, but once we do it's quite strong, and there are some really dynamite scenes as they go through their romantic arc (with action backbone!) that gives structure and tension to the story's climax.
In terms of other gripes, the antagonist feels like he could have done more. There's a fair amount of threatening and antagonism, but it doesn't seem to get towards any really big master plan from a villain who feels like a big mastermind who should have a big master plan.
That's a minor quibble though. The fact is, Master of Electricity will entertain you. It will probably remind you why you liked Urban Fantasy and the endemic Urban Fantasy tropes the first time you saw them, because when something is done well it doesn't matter that it's been done before to some degree. This is done well. It's an old friend in a new face and if you like Urban Fantasy you'll find yourself smiling as you read it, rooting for its heroes and rolling with the punches that the villain throws. It's a nice little bite-sized sample of literary comfort food and I am here for it.
