This is an excellent product. This is a system neutral sandbox. It has several plots, a good cast of npcs, and a GREAT setting. Seriously the land of Brycshire is highly emotive and memorable.
This will form the basis for a memorable campaign.
On a plus the author is really awesome.
There are some negatives. The setting being so unique and remote it will be hard to weave other published tales into the campaign.
Second whilst the npcs have their relationships described very few leap off the page and play themselves, you either need to plan them, or be very quick on your feet to play them.
My last point is locating information in this book can be hard. There is no index and I've been grateful for the pdf a number of times.
It is still an awesome adventure much better than 99% of them out there.
[5 of 5 Stars!]
