Without a doubt - Roswell. If you like JLA's Lux series, you'll LOVE Roswell. There's Aliens and lots of intense kissing.
It's supercharged and superfun. DRAMA EVERYWHERE. Also, the series poetically begins and ends. Novel lovers will love the symmetry of the narrative. GO WATCH IT. Also, this is for Parajunkee's bloghop so please follow her and Alison and follow me and everyone else.
