I have a Nexus 7, Moto X, Kindle Cloud, and Kindle PC also registered. I deregistered them all on Amazon site. Then I removed "The 5th Wave" from my Now Reading Collection on my Paperwhite 2.

I re-registered my Kindle app on Nexus 7, and the second it opened..."The 5th Wave" popped back up in my Now Reading collection on Paperwhite. It is like there is literally no way to get "The 5th Wave" (and about 10 others) disconnected from a collection on Amazon's cloud server. And again, these books are sideloaded ONLY on my Paperwhite. I guess I may try sideloading it on the Nexus and then remove it...maybe that will do the trick.

edit

ok, doing my last suggestion and just sideloading the books in question to the Nexus and adding/removing them from collections there seems to update the cloud..and they now pass that new info along to my Paperwhite. This just tells me that changes made on Kindle for Android actually update the cloud and other devices...but when I make changes on the Paperwhite they don't always stick.

This whole cloud thing is nice in theory, but horribly implemented/tacked on in the last few months. They need a complete, master, web-based Collection Manager that lets you do everything and decide what to sync where. Cause it's so fragmented to me right now.

Anyways I'll keep messing with it...thanks for letting me basically talk to myself as I'm working on this tonight. It's therapeutic!

And thanks nynaevelan, your advice was very helpful!!
