Project Metropolis by rosesmove. Pete POV, Clex, and a really *great* car race.
The greatness here is in Pete's fabulous voice, just as I see him in canon, and all the *detail* she gives us about both the cars and the race. And not in a boring, PSA way either, which is a relief, considering I know *crap* about racing. It's a fun, quick, fascinating read straight through, as Pete gets to know Lex through the medium of cars and Clark and Lex get to know each other all over again.
Seriously, it's a must-read.
