Retrieve custom fields from parent table and and some other custom fields from child models using with in Laravel/Eloquent

i'm having the following issue on a projetct, i'm trying to retrieve some fields from a model and other specific fields from a child relationship, but when i use the ->select('id') statement, it just retrieve the id field from my parent model and all child relationships comes as null values, for example:

$someData = App\Book::with(['author:id,name,email', 'publisher:id,name,address'])->select('id')->get();

I just want to retrieve the book id; the author id, name and email fields and finally 'id, name and address' fields from the publisher table, this is clear? Can someone help me?
