The Midnight Library Chronicles

In a quiet, forgotten corner of the city, there's a mysterious library that only appears at midnight under the light of a full moon. The library isn't ordinary-it holds books that tell the stories of those who visit, but with a twist: the endings change based on the reader's choices while inside.

Main Character:
Elliot, a skeptical yet curious teenager, stumbles upon the library while searching for his missing best friend, Lily. The last clue she left behind was a cryptic note that read, "Find me where the stories write themselves."

Conflict:
Inside the Midnight Library, Elliot discovers that Lily is trapped within the pages of an unfinished book, a prisoner of her own choices. The librarian, a shadowy figure known only as Quill, reveals that the library is alive and feeds on stories. To save Lily, Elliot must venture into different story worlds, rewrite their endings, and face challenges that test his courage, wit, and resolve.

Twists:

Each story world is based on Elliot's suppressed fears and regrets, forcing him to confront his inner demons.
Quill has ulterior motives-he's bound to the library and needs Elliot to complete a specific story to break his curse.
The final twist: Elliot discovers that the library is connected to his family's hidden past, and freeing Lily might come at a personal cost.
