I'm trying to create two content types at once in one form. One is a parent page the other a child page So I'm workoing on a story archive website and I've created several interations using the Book module in drupal. However while I like all the stuff book does by default I need to streamline the process of content creation and I'm no longer sure I can do that easily with book module. 

I am right now trying to figure out how to create a way to create both the front page and the first child page of a story/book in the system, and create an easier way to add a chapter to a story and tell drupal what the chapter number is. If anyone has any advice on this I would appreciate it emensly.
The Inline entity form module was built for pretty much that exact use case:


  Provides a widget for inline management (creation, modification, removal) of referenced entities.
  
  The primary use case is the parent -> children one (product display -> products, order -> line items, etc.), where the child entities are never managed outside the parent form.
  
  Existing entities can also be referenced.
