so

this book convinces, in comparision to others, through.... for example by it's funny language

würd's so übersetzen, wenn es nicht ganz förmlich sein muss =)

@2:

Und was genau soll bitte "... by it is funny language" heißen?

I wouldn't use "convinces" in this context; maybe the book is convincing, but even that seems a bit far-fetched and has a different meaning, anyway.

Maybe something like "Compared to other books (of this genre), "Title of Book" has the advantage of being very funny / using a humorous approach ...

@ 3:
tut mir Leid, da hab ich mich vertan, aber ich denke es ist klar, dass lediglich its gemeint ist. da wird sich ja wohl keiner vertun beim Lesen ;-) oder neugierig?
