Reddit mentions of Smile

My kid is absolutely bonkers for Smile, as are most kids in the early grades. It won an Eisner so it's apparently very good.

Also I highly recommend Jem and the Holograms. The first issue was free on Google Play and my kid practically begged me for the rest of the series.

Plus others have mentioned Adventure Time comics, I think there was a Marceline and Princess Bubblegum mini a while back.

  EDIT: removed IDW's Transformers

The Hilda series by Luke Pearson is really great. I think Hilda and the Troll is the first one, but I don't think they necessarily need to be read in order.

Also, all the Raina Telgemeier. She has Smile, Sisters, Drama, and Ghosts, as well as graphic novel versions of the Babysitter's Club books that are fantastic. And Roller Girl by Victoria Jamieson.

I have a friend with an 8 year old daughter. Can speak from experience that she's addicted to these:
