When a young fantasy writer encounters a bad boy erotic fiction author, she must learn to escape her fantasy world to revel in her new reality.

Agreed with the above comment.

In addition, what is it that the main character needs to do? As learn to escape is a vague description of the story's main action.
To learn is an inner process and will not make for a very good cinematic action, the logline needs a specific objective that she would need to achieve which will clearly indicate that she has successfully learned a lesson.

I am having trouble with "escape" that implies being trapped. ?That she is somehow wanting to escape, if so, why? ?What is the new reality? What is stopping her? The story is unclear.

is she keen to start a relationship and the only thing stopping her is she is mad and lives in a fantasy world.
