I'm pretty sure I've dropped some spoilers around the road, so thread with care. ;)
It's a new adventure for Rafe Kachadorian, our beloved creative middle schooler, who decides to start a business, this time, in order to save up some money for a gaming console.
The idea comes rather quickly, one day right after his mother's scolding him for forgetting to walk his dog, Junior. Naturally, his business should be centered around walking the neighbors' dogs for a small fee.
As always, we are exposed to his daydreams where he manages to build a whole business empire where his dog is the Vice President along with his best friend, Flip. And, of course, his family is no longer poor, his mother doesn't have to work extra, his grandmother has her own private island and, surprise, surprise, his little sister also receives something - a pair of socks. Now, even though he mostly claims that he does not care for her, he still shows the contrary through all the little things he does, one such example showing up right at the end of the story, for instance, when they finally get the gaming platform and they are seen playing together. It's actually refreshing to see them get along and quite the treat, even though miscief still rules their relationship.
Sadly, Rafe's still a magnet for trouble throughout the entire book even though this time it's not entirely his fault. Furthermore, he does show some signs of improvement, of growing up, as he constantly tries to think in a more mature way and solve things the adult way rather than being childish and acting on his first impulse as he usually did previously. The problem starts when a pair of twins decides to crpeate a business similar to his and then he finds a poster of his competitors' business replacing his own at the dog park. Naturally, he believes that the twins snatched his poster, threw it in the bin and replaced it with their own. Of course, as soon as he gets the chance, he does the same: he throws the competitors' poster in the trash bin and puts his own up thus marking the beginning of the war. Afterwards, he also learns how the evil twin geniuses stole his customers and even pull pranks on him by calling his neighbors in advance and pretending to be him. He claims he started the war, but the truth is a bit more complicated, really.
Back to Rafe, the sad part is, he still has no self-confidence and he still views himself as being on the losing side regardless of his actions throughout the story. But there are also some moments when he does actually apprecite his own actions and trusts his judgement. In a way, the author managed to portray how growth is anything but linear. There are, of course, ups and downs. One minute, Rafe is all mature and discusses his issues with his mother, the next he stoops down to the twins' level and fights them in the same manner. It is thus not surprising when everything backfires.
Towards the end of the story, he finally decides to go by the principle of united we stand, divided, we lose. As a result, he finally teams up with his sister, Georgia, and continues the business together, on top of fighting against the twins. The results are impressive; after only two days they manage to get back their customers, earn some more, and even break the twins' reign of terror.
However they later learn the truth behind the missing poster and, since, surprisingly, it is not the fault of the twins, Rafe decides to take responsibility for hsi actions and apologize for all his wrongdoings. However, since the twins refuse to listen to him, he finally does the first thing that comes to mind and cuffs himself to one of them. Once again, his luck is terrible as things don't go his way and he ends up creating more trouble at the school's carnival.
Overall, the story is quite simplistic (it's written for kids after all) but one thing that I really liked was how natural the character's actions were and how easily they flowed. Also, what I enjoyed most about Rafe's character was, besides his creativity, that whenever he mentioned his sister, he showcased a little bit of care, and even though we know from "My Brother Is A Big Fat Liar" about her disability, he never mentioned it and even drew her as prettily as possible. Talk about brotherly love.
