Hello and Welcome to JustAnswer!
Try a reset on your kindle as follows:
Slide and hold power switch for 20 seconds and release to turn it OFF.
Wait for a few seconds and then slide and hold power switch for 20 seconds and release to re-boot.
Now check if the problem persists.
The problem with the book returning to the fist page is corrected but I am not getting the books that wewe ordered. Do I need to reorder?
You can re-download the books.
Thanks. They are just now showing up on my homepage.
