Reception
The School Library Journal praised the book's "metafictional humor", a staple of the series, and found the main character's "changing perceptions of his parent [...] particularly interesting." They also commented on the plot, which might be complicated to follow at times, as well as the plots that are left open for a possible sequel, but ended on a high note, saying that "[b]eneath the wild humor, there are surprisingly subtle messages about responsibility and courage."
