Coyote Falls is one of the best written and developed SAS products - it's a story you can use in any World of Darkness game, whether Werewolf, Changeling, or even Promethean. Better yet, Coyote Falls is a story based upon moral quandary, not just mystery or combat.
This SAS includes 9 scenes for low power characters, with a variety of challenges for the intended Werewolf setting. Coyote Falls is also careful to only give a skeleton structure to its adventure, allowing storytellers to slot it into their game easily, and flesh out the story further.
Specifically for Werewolf: the Forsaken storytellers, this SAS includes a Magath antagonist and another Spirit you could get a chronicles worth of mileage out of. Additionally, each scene describes the local spirits, which could be a quick reference for scenes in a separate story.
In all, this is a fantastic product and well worth the price of admission.
