This isn't a bad summary (can't vouch for the fic; didn't read it), I was just really amused by one phrase:

MPPW era. Severus Snape exchanges school yard torment for the dubious succor of Lucius Malfoy, losing his shot at Lily Evans' love along the way. Double-shot. Mature content.

"Dubious succor of Lucius Malfoy"???

I like.

(I think Wormtail is a little annoyed at having his name moved out of its canon position in the phrase "MWPP", though. And anyway it doesn't scan. DAH dah DAH dah DAH dah dah DAH, wot?)

Everyone must instantly go look at the totally awesome Severus and Regulus art that lily_hbp painted for me. YES. INSTANTLY. THIS MEANS YOU! NO DAWDLING!
