I stumbled upon the sentence:
This book is dedicated to my mother, who has taken care of her family throughout her life without the slightest negligence, in addition to being sincere towards her duties as a school teacher, [...]"
I was wondering about the "in addition to". Grammatically, the preposition "in addition to" is correct, but for me, as a non native english speaker, it reads strange. Probably because of the following "being".
Wouldn't one rather use a "besides" or "in addition of" instead, or is an "in addition of" generally wrong?
