It's on itch.io over here, and you should read through it, leave it a positive review, and let it inspire you. This entire section of my website will be dedicated to trying to describe the way this TTRPG has made me feel and why.
Please note!! Snow is currently taking preorders for a new print run of Songbirds 3e! You can check that out here! It needs 200 preorders to ship, and a game like this deserves a nice print run with a beautiful cover, so consider tossing a preorder Snow's way. Also, you should follow her on Patreon. She's doing lots of cool stuff there in terms of writing and TTRPGs.
