Hi, sorry to dissapoint you, but Im not a Turkish native. I lived in Turkey about 6 years. Unfortunately, my Turkish is not very good, but not bad too. I never went to a course and I never had a book, but living between Turkish people helped me a lot.

I just know, as a rule, in Genitive case, that every time a noun ends in k this will turn into ğ before adding the proper suffixes:

Melek - Meleğin kitapları - Melek´s books

I am sure a native Turkish can explain better
