If any one can help me find this fic it would be great. It is a Riddick/Harry slash/crossover and unfortunatly I can not remember who the author is. I had it bookmarked but it does not appear to be here anymore and it was one of my absolute favorites. It is called "Light My Fire" and Riddick, now lord Marshal is thrilled to finally be able to find his mate on Earth but Harry, who was once a Furryan named Jaden, doesn't want to go with so he and a pregnant Hermoine are knocked out and whisked away. Jack/Kirra is also alive in this one.
If anyone could help it would be greatly appreciated :-)
