Day 01 – A book series you wish had gone on longer OR a book series you wish would just freaking end already (or both!)
That said I think I'm leaning towards Tamora Pierces Trickster series, with Tricksters Choice and Tricksters Queen.
For a series that has gone on much too long I'm tossing up between a few again. There was one I read in high school that I can't remember the name of for the life of me, though I can picture the covers. Seven books of the same thing. If I remember what it was then I will come back and edit this entry.
