I saw this at the library and it piqued my curiosity.
No, this is not about the Fed and money printing. It's a pretty good story about a teenage boy who gets a neglected orchard up and running. It turns out to be a lot of work, but there are lessons about entrepreneurship, supply and demand, honoring contracts, figuring things out without a lot of adult (or state!) supervision, and other themes that would warm the hearts of libertarians everywhere.
This is "junior fiction" aimed at 5th to 8th graders, so kids in that range may find this a good read (as did I, an adult). It's uplifting and instructional, without being preachy.
I thought about writing a more detailed review, but there are a lot of good summaries on amazon, so I'll just point it out.
