Fandom Category: The Pretender
Pairing: Miss Parker/Jarod
Fic Title: You Run, I Chase
Rating/Warning(s): Teen, no warnings given
Why This Must Be Read: It starts out like an episode, and it just keeps getting better and more complicated. It's pretty much everything I loved about the show, and it explores the super-complex past and background of Jarod (no last name) and Miss Parker (no first name).
Fandom Category: Star Wars
Pairing: Mara Jade/Luke Skywalker
Fic Title: A Journey of Discovery Book One: Pendulum
Why This Must Be Read: An AU to beat all AU's. It was down to this or Drive You Mild, but I didn't have to choose between the two as that one has already been recced at this site. Slow development of characters and relationships, and the whole cast has something to do. Plus, just the first book in the series!
(technically, this is my third pairing rather than my first, but the first two don't really have any fanfic to speak of)
