Yes, the same Squaresville from ff.net and AO3.

Hi! I'm a fanfiction writer for the Arthur fandom. I currently have four stories under my belt in a series called "A Different Point of View". In this series, Arthur's class has been aged up to around 14-15 and are in eighth grade. Set in 2009, these stories feature an ensemble cast of characters made up of familiar faces from Arthur's gang as well as some adult characters, so there are multiple character viewpoints and multiple story arcs to explore. The series begins with Buster, along with the help of fellow detective Fern, solving the mystery surrounding his parents' divorce, and he is not prepared for what he discovers. Meanwhile, other characters' personal struggles begin to surface, raising other questions. Why are Muffy's father and brother at odds? What terrible thing caused Alan (The Brain) to be so distant? What huge secret is Catherine Frensky hiding from her boyfriend? And why do Arthur and Francine insist they're not dating when they so obviously are? There are plenty of mysteries to unfold, secrets to be revealed, revelations to be made, and yes, even some romance. And the series is far from over.
On the Long Route, the first story, is up in its entirety, with its follow-up, Lies and the Lying Parents Who Tell Them, to begin posting very soon. Of course, the rest of the existing stories will follow after that. I am currently working on the fifth installment, which picks up immediately after the events of story four. I hope you'll stick around and remember that feedback is always appreciated!
