The kids eat em up
We stumbled on this series as the kids wanted some mysteries and we are reading them one after another. They aren't great, but the kids love "em. The "mysteries" are not scary, but still they keep the kids wondering what's going on. Another interesting thing is the pacing, the story is only 10% about the mystery and the rest is the 4 kids being wholesome nice kids having adventures. The gender politics are hardly advanced, but it leads to a good discussion of how things have changed since there father was a boy.
