It's...fine. I didn't find the plot very compelling (you travel, you have some random encounters, you arrive at your destination, and then you fight some more random dudes), and the layout was a little confusing (lots of pieces are presented out of chronological order, making it tricky to follow and forcing a lot of flipping back and forth). I like that the adventure doesn't necessarily run the same every time—but at the same time, I'd much prefer that be because the adventure allows for lateral thinking and multiple paths to victory, rather than because the adventure gives the DM the option of making the players fight goblins or zombies in the totally self-contained random travel encounter. So, like, it's fine, but nothing especially impressive or amazing.
