Almost a year in the making, I now present... Path of Sorcery!
Path of Sorcery overhauls all 6 magic perk trees, providing more interesting perk options, better ways to role-play, and a more well-rounded magic progression system. Construct a skeleton army, win favors from your patron Divine, unlock the secrets of Daedric artifacts, fuel your spells with the power of blood, weave shadows and control minds - and so much more!
If that sounds interesting to you, follow the link below to the http://www.nexusmods.com/skyrim/mods/68587 page to get more info and download the mod.
