Second person books, especially “Socratic SPBs”, are aimed to provide Socratic Pressure while exploring the contents of (mainly) non-fiction books.
The interaction with the books could be an interface between some narrator of the book and the reader, who communicate directly.
This can also be done in a style that uses the Socratic method, where the book asks questions, instead of the reader asking questions to learn more.
An author can configure the principle concerns and main questions, and what could count as suitable answers, and so on. (My thought here is that this is doable with some of the existing LLM technologies.)
In a fiction context, different parts can be read as books: here’s a dialogue between characters, and, like an RPG, the user guides and is guided through the world.
