OH JOHN RINGO NO!
Perfect review of the Ghost/Kildar/et al series, and yes, I have all but the latest. They are a lot of fun, but they are among the guiltiest of guilty pleasures. Like eating Peanut Butter Captain Crunch in bed, straight from the box.
(A big H/T to Unix Jedi. Thanks to that link, my sides hurt from laughing before 6AM.)
