I've tried (and failed) to make it through a handful of the younger Herbert/Anderson Dune books. They weren't really bad per se, but they lack even a whiff of the profundity of the elder Herbert's work and there just wasn't anything of consequence happening to hook me. That said, I plan to give 'em another go w/The Butlerian Jihad here soon. Reading; The Ghost Brigades by John Scalzi, the second book in his "Old Man's War" series. Quite a bit different than the first book, this one being told third person vs. the original's first person, and w/a different protagonist to boot.
