The Colors of Magic

Jamie, Diego, and Raven have run the gauntlet of magic school together, defeating ancient dangers and saving countless lives. For all the good they've done, though, the powers that be aren't about to bend their rules to allow the three of them to become mages together. No, a mage needs a single partner, a single Complement to unleash the full potential of their magic. Or so the school authorities believe.
What is written on the hearts of Jamie, Diego, and Raven might be enough to break not only the long-held traditions of the Hegemony, though — it might just break magic itself. Can the three find a way to avoid choosing one true pairing, or will they find that the colors of magic are a rigid black and white?
