More an adventure concept than an adventure proper, with a lot of detail left to the DM. But to be fair, it is a "one page adventure", and the concept itself is fine. You also get a new feline PC race with an interesting origin, which is neat.
Very simple adventure that is more an encounter than anything else. Would probably take about two hours or so to play through in your group, and can lead to some interesting things for creative DMs. 5 star sfor being exactly what it says it is, and for offering a free race inside as well.
