Aside from the early Vito Corleone days, nothing depicted in GFII is covered in the novel. All of that was an original story for the sequel to The Godfather.
Anyway, it's apparent from Kay's final scene that the children are indeed raised by Michael...with the help of his sister Connie and the nanny who is seen waiting when Kay is saying goodbye to the children.
Until GFIII came alone, there was no indication as to what Kay's life was like after she left Michael.
