Initialize a reference to an object in the .h file

I have a problem, when executing the next initialization of a reference to an object in the file.h. In principle, the compiler does not show any kind of problem:

class Book{
public:

   Author author2=Author("julio","[email protected]", 'm');
   const Author &refAuthor=author2;
}

I also tried:

class Book{
public:
    const Author &refAuthor=Author("julio","[email protected]", 'm');

}

But when I launch it in debug mode. After calling the print () method

   cppDummy.refAuthor.print();

It shows me, what I attached to you in the image, it's as if the created Author object had not been assigned and had the empty attributes.

What am I doing wrong?

Author.cpp class

 Author::Author(const string & name, const string & email, char gender) : name(name) {
     setEmail(email);  // Call setter to check for valid email
     if (gender == 'm' || gender == 'f') {
        this->gender = gender;
     } else {
     cout << "Invalid gender! Set to 'u' (unknown)." << endl;
     this->gender = 'u';
    }
}
void Author::setEmail(const string & email) {
   // Check for valid email. Assume that a valid email contains
   //  a '@' that is not the first nor last character.
   size_t atIndex = email.find('@');
   if (atIndex != string::npos && atIndex != 0 && atIndex !=  email.length()-1) {
        this->email = email;
   } else {
        cout << "Invalid email! Set to empty string." << endl;
        this->email = "";
   }
}
