OK—but read with your kids to discuss gender & racial stereotypes
My son loves these books, comics, chapter books, all bazillion of them. Mostly I enjoy their combination of education and adventure. However, many persistent tropes of sexism and racism/xenophobia stand out.
The new series of comic books, "Geronimo Stilton, Reporter", might help revive journalism among the young. That's a good thing. But the first book in the series has a stupidly sexist twist, and the bad guy is a presumed Indian raj in a turban.
The older ones are a little more benign. However, expect to interrupt your youngster to talk about gender attitudes fairly often.
It would be nice if the Common Sense review icons added something along the lines of "Gender stereotypes" and "Racial stereotypes" along with "Too Much Violence" etc.
