I would wait a little bit before getting into HTRYC, I found it a little tough at first (I was 1900 online and climbing before I timed out of a bunch of games). Maybe start with it when you hit 1800 online or something.
I have no clue about Yusupov's book though.
I'm studying "Build up your chess". It's a lot of hard work and difficult (but totally worth it - since I started I gained a little over 100 point in my CC rating).
However, I think it might be a bit over your head considering your rating.
Maybe you could start with a good tactics book.
Good luck with your purchase !
I agree with Patate, Build Up Your Chess is quite difficult.
Maybe a tactics book would be a good purchase, Martin Weteschnik's Chess Tactics from Scratch is good.
Probably a tactics book first would be most helpful. Scottrf has made a good suggestion if you're an adult learner (new to chess 30+ yo). If you're younger, here are a couple of other suggestions :
Yusupov's books are much more difficult, and you should study them only if you're really serious about your chess (playing OTB and shooting for a high rating), else you may find them dispiriting
Check out Coach Heisman's web site (danheisman.com) for his book recommendations. Not that you haven't gotten good suggestions so far, but Coach has a whole list of books he recommends and why. Like most of us you seem to want to study calculus before algebra....(and I have a bookshelf full of "calculus" level unread chess books so try not to duplicate that mistake) 
Here's another tactics book that looks like good bang for the buck. It's relatively new, so it may not be as well known as the others mentioned so far.
Here's an excerpt to give you an idea of the difficulty level.

The Stappenmethode ("steps method") is used by the Dutch chess federation to teach kids. An American site for them is here: http://www.chess-steps.com/ They remind me of Yusupov's books in that there is a big emphasis on exercises, and a mix of subjects. Mostly tactics though.
The workbooks are most important, they're only $7 each. I don't think the manuals are that important, it's exercises that count. Step 1 starts at beginner level, the end of step 5 is probably 1900-ish.
I would do workbook 1-5, and if can do step 5 well, switch to Yusupov.
Thanks for the advice, I wish I had waited a day to read these comments before I ordered yusupov's book, but I already ordered it. That's OK I can buy a more appropriate book after awhile. This will be the first chess book I've bought, and I have played 30+ years:-)

You're in for some shock then 
To make good use of this book, try to follow Yusupov's recommendations closely.
However, you should really supplement this with some more basic tactics book... Keep us posted !
If you are serious about chess, Yusupov's books are really nice. I have the first three (Build up your Chess Fundamentals, Boost your Chess Fundamentals, and Evolve your Chess Fundamentals; they're all orange) and they are absolutely kicking my ass. You get 3-4 pages of sample positions explaining a concept, then you have 12 exercises to complete. The exercises can often be very hard, and you will fail many of them. If that doesn't scare you off and are ready to take the time (and pain) of doing the exercises seriously, I heartily recommend them.
Also, the Yusupov books are very beautifully type set, nice font, good figures, nice looking cover art.
I find the tactical chapters arent that hard, mating motifs, pins etc, but some of the strategy ones I'm almost clueless: centralization, outposts etc. Really shows your strengths/weaknesses. Yusupov that is.

Looking at these books on Amazon, it is very confusing. There are nine books in all, but it is not clear if they are second editions or originals. For example:
Boost Your Chess 1: The Fundamentals (Yusupov's Chess School)
Build Up Your Chess 1: The Fundamentals (Yusupov's Chess School)
Chess Evolution 1: The Fundamentals (Yusupov's Chess School)
What is the order here if each is unique? Do you begin with Build Up 1, then Build Up 2, or do you work through Boost, Build, Evolution 1, then Boost, Build, Evolution 2, etc. Very confusing as to where to begin and what each book covers.
you're supposed to do all of the level one books first, build, boost, evolution. then do level two, then level three.
The order is:
Fundamentals (Stage 1); Build, Boost, Evolve.
Beyond the Basics (2); Build, Boost, Evolve.
Mastery (3): Build, Boost, Evolve.
The order is:
Fundamentals (Stage 1); Build, Boost, Evolve.
Beyond the Basics (2); Build, Boost, Evolve.
Mastery (3): Build, Boost, Evolve.
Orange covers, then blue covers, then green covers.
Thanks, @Scottrf. That makes sense. It might be better if they books were sequentially numbered.

They sort of are, the Fundamentals books are numbered 1, but it's not exactly clear, and you have to know the order they are designed in.
What doesn't help is that I've seen places selling all of the build books as a set.
The real problem was the English translation publishers. The publishers wanted to get books out for different levels relatively close together. So they translated all the "Build" books first, then they translated all the "Boost" books and they just finished the final "Evolve" book.
Since the levels are numbered, this means the distributors got a set of books all titled "Build Up Your Chess" numbered 1, 2 and 3.
So they made the incorrect, but quite reasonable, assumption that this was saleable as a set.
And this really harmed the books for the English language market because the first people buying these books that are suppossed to be for 1400-1500 players would play through the first book, and it seemd pretty good, then they'd play the book with the same name and a #2 on the cover, and it would be like running into a brick wall.
It's taken a long time to get the word out about the correct order, but the distributors are still clueless.
Which book should i buy first "How to Reassess Your Chess" or "Build Your Chess" ? I plan on buying them both eventually but I only have a $25 amazon gift card. Based on my blitz rating of about 900 and my online chess rating of 1500 which do you think i should purchase first? I have heard good things about both authors, I will make my decision based on votes, thanks
