I heard about this series and although it was an interesting premise (basically anecdotes from one day-in-the-life of titular Moxy) I didn't really think it lived up to the hype. Although the story arc was believable, the light-hearted and breezy storytelling didn't match its gravity. (Moxy & brother end up being denied a trip to see their father, now divorced from their mother, b/c he has blown them off for a "big Hollywood opportunity.") I think that this writing style works best when the content is congruent with the concept.

This could be a great quick read for proficient readers in 3rd to 5th grades. After all, hasn't everyone had to learn about spraypaint the hard way?
