I trust and believe that you would get some help - fairly fast if you post your question in Adobe InDesign forum.
I also believe that there are fairly few articles posted in InDesign articles on how-to create e-book. I see that you are new to Adobe product(s). I would think you also get some informative/educational training, at a fee, at lynda.com website. At Lynda dot com, there are many excellent resource and tools and books about how to get most out of Adobe apps.
Thought this be of an interest and help.
Best of luck!
Moved from the Creative Cloud to the InDesign forum. They will be able to help you here.
