"Time is the most fluid medium in the universe; humans are its most replaceable element." There are rules for traveling: A mage must never go forward. Keep the secrets of the order in all times. And never, ever travel during the thirteenth month. Born into a powerful mage family, Narine Anahid Khoren is a time traveler whose life is constantly in flux. Since committing to the order of the Seba Segal at fourteen, she's spent her life traveling through history, trying to make a difference and sacrificing her life in the present for one jumping through the past. But while the world in 2071 has moved forward, the ancient order of the Seba Segel have become ever more archaic. The secret sect founded by astronomer priests has passed its magic to thousands of generations, perfecting the secrets of divination and time travel, while also amassing power, influence, and riches. Change is on the horizon, and some in the order would do anything to stop it from coming. When one of the highest laws of mage travel is broken in the thirteenth month, Narine, her friends, and one unsuspecting professor will have to scour history to set the timeline right.
