The writing is filled with all manner of odd, anecdotal bits that don't have much to do with plot development, but everything to do with getting a laugh. Butt lasers, sparkle bombs, Nilixian Rootbeer and mind readers who have dyslexia. It doesn't hurt the nine-year-old knee slapping factor at all that many of these items (Spleen Island!) are accompanied by pictures.
Patterson has quite a collection of books he has written with others under the "jimmy" imprint, so as Middle School: The Worst Years of My Life and Treasure Hunters, but it is good that he is letting other authors have full credit in his new line of James Patterson Presents Books. Even the most reluctant reader won't be too disappointed to find these books wrapped up as gifts!
