Otto and Raven are desperate to rescue their friends from the clutches of Anastasia Furan, head of the evil Disciples organization. First they must track down the location of the Glasshouse, the prison where Furan trains children to become ruthless assassins. But Otto is also being hunted. In the three months since his "expulsion" from H.I.V.E., The Artemis Section--an elite intelligence division that goes after the toughest targets and reports only to the US president--has had an opportunity to locate him. Set against the backdrop of a daring high-tech prison break, nothing is quite as it seems in Deadlock.
