It's not really a second edition, it's jut a revised version, which also includes feedback from the readers.
Visually more appealing, less typos and a couple of additional paragraphs.
If bought the book, write me an email with your photo holding the book, and I will send you back the pdf of the new revision. Offer valid until February 24 (excluded).
On February 24, I'll collect all the eligible recipients and send the file.
Please, state explicitly in the email if you allow the photo to be published on this site.
