First in the Alex Rider series, teen Alex is recruited to save the world, or at least the U.K., from free poison computers. Quite a lot of graphic violence, I thought, for a teen book. Get off my lawn, you kids!
A thirteen-year-old lad and his somewhat dim older brother run a rather unsuccessful detective agency. Somewhat bloody for middle school, I thought. But then, thousands are killed in The Lord Of The Rings.
