Always/Never/Now starts at Lady Blackbird and takes off in its own direction. It's an adventure with the rules for a full game built right in.
The attached characters are great. They have strong, well defined starts, and room to grow.
The story is only somewhat fixed, but by following the setup it's fairly easy to make your own adventures in a similar vein.
Already running it with my group, and I have to say everyone is enjoying themselves immensely.
