A covert witch and an enigmatic vampire break taboos as they join forces to unravel an ancient text that could save — or destroy — the magical world.

Matthew and Diana travel back to Elizabethan London, where they are hiding in time from the Congregation. Here, they must find a powerful witch teacher to help Diana control her magic and search for the elusive Book of Life. Back in the present day, Diana’s beloved aunts must take shelter with notorious witch hunter Ysabeau De Clermont at her ancestral home.

In season 3, the final season, Matthew and Diana return from their trip to 1590 to find tragedy at Sept-Tours. They must find the missing pages from the Book of Life and the Book itself before it’s too late. Their enemies are gearing up against them, and a monster from Matthew’s past who has been lying in wait will return for revenge.
