I've spent the evening happily devouring the Yuletide offerings in my favourite fandoms, and I'm sure I'll come back with a much bigger rec post in about a week or so. But this particular story COULD NOT WAIT. It's just one of the very best things I've ever read.
If you're familiar at all with X-Factor (comic book, not singing talent show) you'll be stunned by how brilliantly in character this is. The voices, the motivations, the relationships, THE TEAM DYNAMIC - if reveals show that this fic was written by Peter David himself I won't be even slightly surprised. It's that spot-on perfect. The mix of action, mysticism, friendship, romance and humour are all why this is my favourite comic ever, and it's all done so very very well.
It's no secret that I ship Theresa/Monet like FedEx, and this fic turns the currently hopeless state of that relationship on it's head and provides a wonderful (and so believable!) solution. And this is probably the only Moneterry (no idea if that's the actual shipname or I just made that up, but I think I'm keeping it) that I've ever read in which Monet's past with Theresa's father is called into play. The scene with Sean Cassidy (one of my favourite characters in the history of characters) honestly brought tears to my eyes. And it's just one of a million things I could point to that shows how very well this author knows these characters.
So if you like X-Factor, please read this. If you like femslash, please read this. If you just feel like a well-written, clever, spooky romance, you should be reading this right now!
It's called Heartlines and it's here:
