I just got back from uni, and i'll be her till tuesday:
Last week i had started Sensen spike hills, so i guess i'll continue that, but i also felt like i wanted more of WTNHK, so i don't know what will come after. If i manage to resist, i'll delay WTNHK novel/manga some more, so that the desire grows stronger
Now getting again to read, i'll check the other titles you suggested when i finish
SSH, because otherwise my attention could be drawn away from the title i'm currently reading, making me eventually drop it for the moment.
