They enjoyed getting one a month in the mail
Reviewed in the United States on May 10, 2016
I purchased these for my grandaughter. My own children had a set when they were little. They enjoyed getting one a month in the mail. These come in a set of four. I hoped my grandaughter would enjoy them as much. She couldn't put them down. This is the second set I have bought her. I will be adding to them. The stories are mysteries. But there is adventure and creativity on how the children survive. My grandaughter kept talking about the books to her mom. I don't know the age recommendation. My kids were between 7 and 12 when they read them. My grandaughter is seven but reads at 5th grade level. Hope that helps...
