(Confession alert!) I'm having trouble finding the "right" post-series fic. I've started several that seemed quite promising at first but then later went off the reservation character-wise. It's a bummer to start a multi-chaptered fic only to have it wander off into the tangled wilderness of OoC land. I'm not particularly a fan of fluff (especially Fluffy!Brian) or nothing but sex-sex-sex 24/7. I'm looking for something gritty and real and angsty, and the longer, the better. I want something that is going to totally engross me and satisfy my bottomless need for The Feels.
Thanks ahead of time!
ETA: Wow! Thank you all for the response! Some great suggestions in the comments!
