Wonder Woman 228 is a team up between Wonder Woman of Earth-One and Wonder Woman of Earth-Two. After that, from issue 229 until issue 242, the Wonder Woman title stars Wonder Woman of Earth-Two. Wonder Woman 243 is another team up between the two Wonder Women and after that issue the title returns to being about the Wonder Woman of the main Earth.

Has anyone read these issues? Without reading them myself, I'd like to know what the in-story explanation is for the long stretch of issues staring Wonder Woman of Earth-Two.

Thanks.
