and how to map BookDTO to Book and Author?
I used the automapper in my solution.

Answer 1

You could create a mapping for each:

Mapper.CreateMap<Book, BookDTO>();
Mapper.CreateMap<Author, BookDTO>();

And then use it like this:

Book b = new Book { Name = "Gulliver's Travels" };
Author a = new Author { AuthorName = "Jonathan Swift" };

var dto = Mapper.Map<Book, BookDTO>(b);

Mapper.Map<Author, BookDTO>(a, dto);
