There is nothing to say that you must read one book linearly, from beginning to end, before reading another book. That is, you can profitably read/study portions of any number of books simultaneously as it suits your interest/needs at any instant. After all, there are many facets to chess and it is wrong to think that you must master one facet before moving on to another - for example mastering the opening before moving on to mastering the endgame, or tactics before strategy, etc. When you learn something, anything, that results in an improved understanding of the game of chess, that should be considered a success. The process of learning chess is therefore a process of accumulating these small successes in the myriad facets of the game, regardless of which specific resource (book, video, etc.) imparted the knowledge at any given point in time.
You might also consider resources that aid in understanding chess from a positional-strategic perspective, which is a way of looking at a chess position for the purpose of conceiving and executing a plan of action, thus providing a framework for identifying an appropriate next chess move or set of moves...

So I've been reading this chess book "The Soviet Chess Primer" and I mainly decided to read it as a way to form a good base for my chess knowledge as I believed that it was something I lacked even at the rating I am at now (1419) and to also learn more about middle games and endgames improving my chess as a whole. So far I think that its a wonderful book and I've been slowly but surely reading it for the past three weeks. I'm currently at page 48 of the book and just playing through the games I've certainly been learning a lot from it and solving the puzzles are also fun and instructive.
However the dilemma I'm currently facing is that I have three other chess books (How to Reassess Your Chess, The Amateurs Mind, and Chess Strategy for Club Players) all three books by no coincidence are books about the middle game (what I believe to be my weakest skill) and the thing is these books have been tempting me these past three weeks to read them and find out what they're all about and just reading a few pages of these books makes me believe that It'll probably be more beneficial if I read those books instead of the one I have now. But I also want to focus on The Soviet Chess Primer and finish that one first as I've already read it and find it useful.
So what should I do? Should I continue reading "The Soviet Chess Primer" or should I read a book dedicated to the middle game like "How to Reassess Your Chess" and "The Amateurs Mind"
