Series recommendations?

Hey everyone!

I’m looking for dark romance series (not standalones) that follow the same couple over multiple books.

I loved getting more time with the same MMC/FMC in series like {Torment by Dylan Page}, {Graves by Katelyn Taylor} (even though it’s one book, I loved and and read it three times already), and {Little Stranger by Leigh Rivers}. I always get so attached to certain characters, and when a book ends I’m just not ready to let them go yet.

I’m really craving that kind of ongoing dynamic where the relationship keeps developing (and maybe gets even more intense) over several books.

I don’t really have triggers or hard no’s, just not into fantasy (so no fae/demons/etc).

Drop your best recs please!
