[Young Adult Fiction (Ages 12-17) ][Read by Wil Wheaton]Fast moving, passionate, and as current as next week, ''Homeland'' is every bit the equal of ''Little Brother'' - - a paean to activism, to courage, to the drive to make the world a better place. In Cory Doctorow's wildly successful novel ''Little Brother'', young Marcus Yallow was arbitrarily detained and brutalized by the government in the wake of a terrorist attack on San Francisco - an experience that led him to become a leader of the whole movement of technologically clued-in teenagers, fighting back against the tyrannical security state. A few years later, California's economy collapses, but Marcus' hacktivist past lands him a job as webmaster for a crusading politician who promises reform.
