I love this genre, but…

with the recycled story lines, same MMC and FMC types, tropes and worlds… idk how people keep a series straight in their brain without it melting with the others…Especially an unfinished series. I have so many I’ve started and liked but once a month or two goes by I wouldn’t be able to pick it out of a police romantasy line up. Anyone else struggling with this repetitive memory fatigue?
