My copy of Peril in Freeport (Adamant Entertainment) arrived yesterday, and I'm still reading through it. However, I've already found one serious problem--Chapter 1 is missing a great deal of text--which I've brought to Gareth-Michael Skarka's attention. He plans to make an errata available from Adamant's website on Monday.
Once that's available, and I finish reading the adventure, I'll be giving the book my usual "Errata & Notes" treatment. But I'm not really familiar with Pathfinder, so I'll be focusing on content and not diving into mechanics and stat blocks as much as usual.
I will probably be adapting the adventure to the v.3.5 Freeport campaign that I'll be starting soon, so I may post some conversion notes to my errata wiki as well.
