The Quill of Ages: Cogitari (Edicts and Orders Book 1)

When fifteen-year-old Chloe mysteriously disappears, the rumors at Grammaire Hall point to murder, but spiritual entrapment isn’t the same as dead. Try as she may, she can’t remember what happened to her before she woke up as a spirit in the campus graveyard.
As Chloe uncovers clues leading to the location of her body, a secret the Magical Parliament doesn’t want to get out starts to unravel. Rogue sorcerers have infiltrated the school, intent on reinstating the Third Edict, and sorcery students are dying because of it.
Destroyed long ago for horrific crimes against humanity, the return of the Third Edict would spell disaster for both magical and magicless societies. To prevent her demise and the fulfillment of the Third Edict’s return, Chloe must find a way to reunite body and soul without giving the rogue sorcerers the weapon they need to succeed, a weapon only Chloe’s bloodline can activate.
