Simple ebook reader and organizer for calibre library

I have a lenovos tab a10 I bought for my mom.
I put a calibre library in the books folder as well as on google drive.
I'm looking for a simple ebook reader that can browse the calibre library as well as read the books.
Calibrecloud only browses the library so that is useless.
I have tried Nook, Moonreader, FBReader and I don't like them.
Most of the books are in epub and pdf format.

Thanks in advance.

Solved and did not know how to delete thread.

Gonna use Calibrecloud for her to browse books. Then I will put them in Google books for her.
Their reader is good but only for epubs. Pdfs you cannot change the font size.

Nice talking to myself.
