story begins…
with harry at the top of the astronomy tower contemplating life: possible good fic, keep reading
with harry in his room after fourth year simmering with anger: possible good fic, probably over powered, probably has some Magic Inheritance dealios, keep reading if thats your cuppa tea
with characters from the series finding some books: the entirety of the harry potter series written out again with the characters making indignant comments throughout, keep reading if you dont mind rereading the books again
with harry being horrifically beaten and/or sexually assaulted by the dursleys within the first three sentences (or at all, tbh): bad fic, abort, it only gets worse as you read on, probably has some pedophilic relationships and non-negotiable dom/sub overtones, just leave, run far away
