Ok I'm sure this has been asked before but well here it goes.
I'm after something epic length (Not focused on just high school). Having read at least 3 times each here are my favorites in this category
Mayhem 1/2/3/4
Sword Saint
Hindsight 20/20 1/2 (didn't like 3)
Recluse and Ghost
Tangent
Sea King + follow ons
A fresh start
Banner Year
Can anyone recommend something that is engaging with likable characters

Oyster50's "Smart Girls" stories: start with Cindy, Nikki, and Tina, then Community.
All Smart Girls stories are connected, they are one really epic story arc.
