Hello there, has anyone come across a good fanfiction about Voldemort's years as a student at Hogwarts, preferably as close to his depiction in the books?

 

I'm not sure how you feel about pairing but if you don't mind Tomione here are a few recommendations.

This one isn't really a pairing but has an interesting depiction of Tom Riddle set during his Hogwarts years. It's only a one shot.

This one is also a one shot but it extends with other one shots by the same writer. This is also set during his Hogwarts years.

This one is different from the other two as Hermione is from Tom Riddle's time period.

If you don't like Tomione, oh well. But I like these as they present a Tom Riddle that began to recruit a following and foster an environment where the Death Eaters could rise. I'm almost positive each of them has Tom as a brown noser to the teacher (not Dumbledore of course) but also as the mini Dark Lord. Hopefully that's what you meant as close to his description in the books. Let me know what you think.

 

The Broken Victory by Kate Lynn

I haven't read it in a while but I remember it being pretty awesome, plus it's in the Library with a 5/5.

Harry is accidently transported fifty years back in time through a fluke with the mauraders map. Here he runs into and befriends Tom Riddle, hoping to find his only weakness. No Slash.

If you like time-travel, this fic is one of my all time favorite. Sadly, it is not finished, and clearly abandoned, but I've always liked the depiction of Tom Riddle in this fic.
