I just ran this adventure as the opening two sessions for my campaign with a party of 3 2nd-Level adventuerers. It's very well written, well laid out, and has several interesting plot points that can be picked up in later adventures depending on the PCs choices. There's a good amount of both combat and social encounters. Last night, my party ended up avoiding multiple combat encounters due to a willingness to roleplay and some really crappy rolls from me.
I also really appreciated the setting neutrality of this adventure. I was able to drop it into my own setting without issue - as long as you have a nearby forest, you can run this adventure.
