I found a good Smallville fanfic and as it's so hard to find good ones I 'm recommending this one, if anybody wants to read it:

A Window to the Future by Jadarite_18

Clark rescues a woman that tells him to "save Clark" before passing out. But when she wakes up she's amnesiac and she looks a lot like Lois.

It's a long fic (33 parts). Kryptonsite system is messy (story mixed with FDK) but the story is worthy the work. It's very well written. thumbsup
