If he can’t perform at the highest level, what chances do the Miners have against the unstoppable Neutrons? Worse yet, his powerful enemy, Raiden Zuna, knows Strike is hiding something. Zuna offers to help, and Strike is tempted—but the information Zuna wants in return threatens Strike’s friend Boom, as well as the growing Dark Side resistance.
