My group are getting fairly close to finishing Kingmaker, and we might do some modules for a while before starting the next AP. I thought I'd ask the experts, what are your highest recommendations? Looking for 1e only.
Midnight Mirror is a solid investigative/horror story, with interesting combat opportunities and a lot of opportunity to flesh out and build on RP seeds as your group enjoys. I had a lot of fun running that one, and my players seemed to enjoy it as well.
