Hi Mason,
Thanks for the leeway there on the promotion rules, I wasn't aware and I appreciate having this space to address questions. Let me address yours:
I think it's very normal that our two books cover similar areas as any text that strives to provide a complete course in this format of the game must cover the same bases. In fact this can be true of almost any instructive text. Two books on horse riding, for example, could be expected to cover the same topics, but one could cover them in a more relevant up to date or detailed way than the other. I think there are many major differences between The Grinder's Manual and Harrington On Online Cash Games: 6-Max no Limit Hold 'em.
1. The Grinder's Manual is extremely up to date and approaches the game as it is seen by the top online professionals in 2016. I think that honestly Harrington's book is very outdated now given how far poker theory has moved along since it was written.
2. The Grinder's Manual is a much more academic textbook. The figures and logical thought processes it uses in conjunction with example hands are laid out in a way that is not at all dissimilar to something you would purchase to accompany a university course. I believe poker is every bit as rigorous a subject as any you might study seriously in further education.
3. The Grinder's Manual is written by a professional online poker player who has devoted his career to grinding and teaching exactly this format of the game. I therefore believe my expertise as an author to be completely suited for the subject matter of the book.
4. Finally I think the Grinder's manual has a much steeper progression than the Harrington's book. It quickly moves onto subject matter which is in my opinion much more complicated but totally essential for a strong enough game to succeed at 50-100NL on pokerstars in 2016 and at least the near future. I was very committed to not scrimping on any necessary detail and so the book provides a significant challenge to the newer player right from the start and quickly challenges stronger players by the second and third chapters.
Any other questions I'm more than happy to answer. Thanks again.

I found it in someone else's blog. I really like the structure of it and how it approaches poker like a proper course. Yes it probably over simplifies some things (and not sure what level you are already at) but I am finding it very useful at the very very microstakes of NL5
