The Siege

Gr 7 Up—In The Six, readers were introduced to Adam, a young teen with muscular dystrophy. When Sigma, an AI created by Adam's father, goes rogue and threatens the future of humanity, Adam, along with five other terminally ill teens, agrees to undergo an experimental procedure that will meld his body with a weaponized robot. In the latest installment, Sigma is back and smarter than ever—it now understands human betrayal and plans to use it to its full advantage in the next stage of its war against humanity. Will Adam and the other Pioneers be able to stop Sigma again? Alpert's series is a fascinating tale of humans vs. technology, a conflict that is often missing from YA sci-fi offerings. Give to readers looking for a technology-driven sci-fi story. This series can also be used as a bridge to Isaac Asimov's adult "Robot" series.
