Say you're a Smallville fic writer who wants to include DCU characters in your epic fic novel series but you don't know too much beyond the characters who've shown up on SV, plus a little more than the basics on Batman and Wonder Woman. Say you're trying to take advantage of Amazon's buy-3-get-the-4th-free deal. Say you're trying to decide between
this book and
this other book. Which would you choose? Or would you not bother with either of them? Are there
any others that you would recommend?
