Where did my books disappear to???

[AC Question]

All of my downloaded books disappeared from my device overnight! They appear to be in the cloud but I can't download them! And yes I'm hooked up to WiFi and it is working just fine. I am in the middle of a good book, and I have hundreds more that I want back. Anyone else have this issue? I'm at my wits end here...

What device do you have, and which version of android is on it? Do you know where exactly you had the books stored on your device?
