This adventure series is created especially for readers who love the fight of good vs. evil, magical academies like Hogwarts in the Harry Potter saga, and games like Minecraft, Terraria, and Pokemon GO. The redstone dust has barely settled after Phoenix's epic battle against the Defender when word of a new threat arises: the legendary ghost of Herobrine has been sighted in Phoenix's village, and under cover of darkness, he's terrorizing a new family each night. Phoenix and T. H. rush to the village, where they discover a tangled string of clues. Just as the friends-turned-sleuths are sure they've unraveled the mystery of Herobrine's griefing, they uncover a secret that makes them question everything they've learned. And when a new, stronger enemy appears, their hunt for Herobrine is turned on its end once again. Can a ghost be in danger? And could Herobrine cease to be their enemy and instead become . . . their ally? Fans of Minecraft won't want to miss this gripping, mysterious addition to the series that began with Quest for the Golden Apple!
