After their recent adventures, the Lockwood & Co team deserve a well-earned break . . . so naturally they decide to risk their lives breaking into a heavily-guarded crypt. A building full of unsettled souls, it’s also the final resting place of Marissa Fittes, the legendary and (supposedly) long-dead ghost hunter – though the team have their suspicions about just how dead she might be.
What they discover changes everything. Pitched into a desperate race to get to the truth behind the country’s ghost epidemic, the team ignite a final, epic battle against the Fittes agency. A battle that will force them to journey to the Other Side, and face the most terrifying enemy they have ever known.
Can everyone make it out alive?
