The best kanji book for N2 by far. I spent a whole lot with this one, trying to understand every kanji and even building an Anki Deck for it (753 cards approx). Thereby, the assumption that you will finish and understand thoroughly every kanji in eight weeks is non-sensical to me. Just get on your own pace if you have time, and if not, try to follow the book guideline (which means you have to go through up to fifteen kanjis per day...). Either way, in comparison to the Shinkanzen Master N2 Kanji, Sou Matome handles the learning process smoothly and the examples with context are pretty insightful (although you may feel some kanjis appearing together for a certain topic is somewhat forced, I understand the difficulty of trying this approach in the first place, so it was no big deal).
Despite the obvious flaws, such as the lack of more examples for some words and the overoptimistic schedule, I believe this is the best book for studying Kanji at N2 Level. After studying this one, you can go and practice the Shinkanzen version; it will improve your level a lot.
