It’s been a month since April’s premonition. She is struggling with her magic, the ramifications of her premonition, and the expectations of everybody around her.
With the End of Days averted for now, Jack is reeling from the cost of saving Gaia. With Merlin focused on retrieving Arthur, both Fate and Chaos see opportunities to further their causes, leaving Gaia stuck in the middle of them and defenceless. As April’s premonitions and newfound magical abilities grow, the balance of the universe shifts once more, drawing Death’s attention to April.
And Death does not tolerate an unbalanced universe.
With the odds stacked against her, April must find herself some powerful allies and navigate the many revelations that are heading her way.
