Their Mutant ( HP/X men CROSSOVER) WTM

When Dahlia Potter-Peverrell-Black was in her 5th year, the last thing she expected was to have everyone watching her past and future. Much less find out what her mutation actually was and the fact that her long time friend, Mortem, had gifted her mates.

DISCLAIMER: I don't own Harry Potter or the X men. They belong to their creators, all I own is Dahlia and her plot! This will be a reverse harem type of story. If you don't like it, move on!
