    Congrats! It must be very interesting materials. :)

    Just Noticed: Why is the middle book in the lower line with red word – “Effective” – in the title? Is it a design mistake? because others don’t have it, even in the chinese versions.

    Yes is was a publisher design mistake. I was never sent a proof of the cover so I was not able to see it before printin.
