Help with book reading order

Hello. I recently decided to purchase some used chess books and work my way through them.  I’m interested in improving but not intense about it, will be pretty casual. 

I bought Comprehensive Chess Course vol 2, Chess Tactics for Students by Bain, Bobby Fischer Teaches chess.  I also bought complete chess course, but may just donate that because it’s in descriptive notation and I already have these. 

If I make it through these my ideas for next are Back to Basics Tactics, Logical Chess move by move, and Silmans Endgame Course.  I also had my eye on the Steps Method, what I read seemed interesting and positive. 

So my main question is should I work through one book at a time, cover to cover?  If so which one to start with?  Comprehensive Chess Course?

Or should I be dividing my time between them?

You should definitely read Comprehensive Chess Course cover to cover. You can read the others cover to cover afterward if you want but you will see a lot of redundant information. You could shelve them and use them as resource book and read selectively as needed.
