i've been reading
roman holiday and its sequels recently (actually a re-read, but it was recced to me recently, and i am enjoying it the second time, too). it's hermione/draco and hermione/snape at the beginning, omg, het from me? shocker! anyway, yeah, i know, redeemed slytherins - maybe not so feasible a while ago, but i see more promise in draco after hbp, and i suppose the camp is still split on snape (but i have faith). anyway, i think that there is enough backstory involved here to justify the redemptions - they are still bad boys, just not evil ones, anyway.
so! it's long and chaptered, and i think the third part isn't finished and may never be, but it's an action packed exciting thriller sort of thing with some pretty sexy scenes in it, actually. i'd recommend it, if you have the time.
(as though i do, but whatever)
