C # How do you solve a circular reference to an object

Question

I came across what, in my opinion, could be a serious problem for my code, and I was hoping that someone here could explain to me how I would work on the problem.

I have 2 classes, each of which has the property of another class that creates a circular link. I plan to serialize these classes and use XSLT to format the output, but I assume that this will fail due to a circular reference.

Example

public class Book
{
  public BookShop TheShop = new BookShop();
}
public class BookShop
{
  list<Book> Books = new list<Book>();
}

So, from this example, every book will be in a bookstore, and in every bookstore there will be many books. If I serialize a bookstore, it then serializes each book, which then serializes the bookstore and so on round and round. How should I handle this?

    [XmlIgnore]
    public IBookShop TheShop { get; set; }
}
public interface IBookShop 
{
    void SomeMethod();
}
public class BookShop : IBookShop
{
    list<Book> Books = new list<Book>();
    public void SomeMethod()
    {
    }
}
