Laney Jacobs, The Last Slayer?

Found this AU of When John and Cam met the Last Slayer that I began writing before Laney the Space-Vampire Slayer. Laney doesn't go to Jack, or to Europe, after the others die. She seeks out her on-off boyfriend Dean Winchester with the faint hope that he can fix it, fix her. But do all roads lead to Atlantis, and what will she find there? Rated M for lang/smut (slash/het)
