So, in Morgan Brice's Dark Rivers, we follow Evan and Seth to that known hellhole, Pittsburgh. (At a guess, the next edition will be either Cleveland or Detroit. Witch disciples of the Rust Belt for the WIN!)
Anyway, the general plot is that they've discovered another disciple and descendant, this time living in the 3 Rivers. Said descendant, Brandon, works part time as an EMT and part time as a barista. His boyfriend, Alex, works as a PI, one who Seth happens to have hired. Oops.
Add into this Evan's evil ex, who's now working for the current disciple, and who kidnaps Evan about halfway through, uses Evan's phone to text a break up message to Seth (along with an old non consensual video of him and Evan from back in the day), and you have a whole mess of drama.
While the book was actually well written and a heck of a lot more compelling than much of what's currently being written in the MM Supernatural Romance genre, it doesn't change that this particular story is a straight line. Or that the confrontation that ends everything happens relatively early, leaving us several pages of Christmas good will and...well... stocking stuffing.
Mind you, there are other hunters running through the book, but I have no idea if they're from another of Brice's series or not. (If she's creating a shared universe, that's great. If not, give us someplace to track down what the other hunters are talking about. Actually, either way, show us what the heck the Ninja Priest and Government agent were doing prior to this.)
Fun read, if a bit light.
