Not being able to work on a book was one of the reasons why I switched to OneNote from Evernote. Evernote is very rigid about how it arranges notes and this can be troublesome when you are working on a book.

Forcing Evernote to let you write a book would be like forcing Windows notepad to let you write a book using it. If you are hellbent upon using something, you can definitely use it. The main problem with Evernote is you always have to figure things out in order to achieve even basic tasks like scheduling.
