The Boy Who Unlocked the Universe — T.R. Dillon

14-year-old Radithorne Smith has blood on his hands. And those desperate voices in his head? Well, Raddy thinks they're the people he killed blasting off the Krucifer. Come back to haunt him. As Raddy holds the Sword of Unspeakable Justice -- his birthright! -- in his hands, he wonders whose head it will next lop off. His own? Raddy has just saved the universe for a second time. Just stopped the worst atrocity in human history. Just become the first person to operate a portal in thousands of years. You'd think his life would get easier. But you'd be wrong. As Floor Walkers begin killing themselves in horrible ways, the Mendacians trigger a crisis that threatens to destroy the Boundaries once and for all. Dodging an assassin on DS1, while receiving protection from the unlikeliest sources, Raddy struggles to push aside horrifying visions of the future in order to chart his own destiny. Fleeing her own demons, Betsy returns to DS1 from the Academy to help Raddy find the courage to make an escalating series of life-or-death decisions for the universe. Relying on the dwindling survivors from the Krucifer, Raddy finally decides how much killing is enough. And when an eon of Mendacian darkness beckons, Raddy discovers to his amazement that the last and hardest choices are really the easiest -- so long as Betsy is there to take those final steps with him. "The Boy Who Unlocked The Universe" is the third book in TR Dillon's exciting new young adult science fiction series, "The Hall of Brains."
