Lucy and her friends' time at Minecrafters Academy is coming to an end, and the entire school is preparing for graduation. But when an explosion shakes the campus and Lucy's old friend Steve appears with bad news from his village, all plans to celebrate come to a halt.
The school is no longer under attack-it's being destroyed. And it's time for the students to use their training outside the safety of the Academy. Lucy, Jane, and Phoebe must use the skills they've honed in school to battle the evil force that is taking over the Overworld. But who is really behind the attacks?
Unexpected twists and turns lead Lucy and her friends back to Steve's village, where they discover an unlikely opponent. With help from old friends and fellow students at the school, they stage a battle to save the Overworld. This is their last stand-do they have what it takes to keep their world safe?
Fans of Minecraft and magic academies will be on the edge of their seats in this final installment in the Unofficial Minecrafters Academy series.
