EBook project

Hello fellow Nexus 7 owners,

I have a Nexus 7, unmofied, & still with the factory OS (Android 4.2 "Jelly Bean", I believe)

I want to create an eBook on my PC, then transfer the eBook/file to the N7, and share it with friends.

So far, (this has been an on-again & off-again project) I've created my eBook on my PC using MS Word 2010 which allowed me to save the eBook/file as a .PDF file. This is only as far as I've gotten with this project. What would be a good way to proceed with getting the file onto the N7? (Where on the N7 should it go? How can I share it?)

{I'm an old timer in the PC arena, but fairly new to mobile/portable devices}
