Untitled Sims 2 Of 2

Is slow burn horror a genre?
I'm not an avid horror reader, but I guess 'tis the season. Family Business starts slow, so slow in fact, I considered putting it down around page 130, when still not much had happened. I'm glad I didn't, since it took up quite some speed shortly after that point and came together nicely in the end.
I did like the unpretentious diversity in the novel. The characters and especially Diya's grieving were convincing, and as I said before, I love how Diya makes sensible choices and even consults a doctor in case it's a mental problem. I feel like that doesn't happen often enough in this genre.
