Lilith Restrained is a collaborative story that you can follow on the website chyoa. The idea of this website is that you can follow series you like, and according to the choices you make at the end of each chapters, the story can take you in another direction.
If you wish, you can add chapters and continue storylines by writing your own.
The author at the origin of the story Lilith restrained is Jnightshade. He’s also created the great Hariett Cooper comic series that he’s been making in colaboration with Shinra-Kun (check the link in the 3Dcomics entry if you don’t know about H3ncomics/Shinra’s work).

Lilith Restrained is a continuation of the story Lilith Strain created by Lycanthrokeith. The whole universe of Lilith Restrained takes its origin there. It might be better to start with it, but it isn’t absolutely necessary as Lilith Restrained is quite readable even without previous knowledge of the universe.
If you’re getting a bit tired of reaching dead ends with your choices, my advice would be to register on chyoa then click on the link “view story map” which allows you to check all the storylines and then make your choices knowingly.
