She hung a new sign on the door:

Back at the laundromat, Lila let the shadow taunt her. It lunged—faster than a ghost should be able to move. She sidestepped, uncharacteristically unimpressed.

I need to make sure the story has a clear beginning, middle, and end. Perhaps start with the protagonist facing a problem that her power can't handle, leading her to investigate why. The middle explores her journey to understand her unique ability and the problem's true nature. The climax would involve her overcoming the challenge in a unexpected way, using her hard problem-solving skill in a new context.

Check for themes that Estep often uses—resilience, self-discovery, overcoming fears. Maybe add some dark elements, like a supernatural threat. The ending should resolve the main conflict but perhaps hint at larger issues for potential sequels or series development.

The user might be looking for a parody, a short story inspired by her style, or perhaps they heard about a book with a similar title. Alternatively, they could be seeking a fan-fiction or a related story set in her universe. Since the title mentions "ePub," they might want it formatted as an eBook.

Potential plot points: The protagonist has a power that activates only in the face of hard problems. She faces a dilemma where the problem is too easy, making her power useless. Maybe she needs to figure out how to make the problem harder or discover the source of her ability. There could be a mentor figure or a rival. Conflict could be external (a villain causing trouble) or internal (struggling with her power).

Incorporate elements like humor, action, and character development, which are trademarks of Estep's writing. Maybe include a twist where the real challenge isn't what it seems. Also, considering the ePub format, the story should be concise but engaging, suitable for a short eBook.
