This book is out of print, but still available if you know where to look. John M. Ford's award winning "Growing Up Weightless" is a familiar theme for him: coming-of-age during a period of change in society. His version of Lunar society owes some debts to previous stories including Heinlein's 'The Moon Is A Harsh Mistress,' but has developed in ways that may surprise you.
As usual, his story is multi-layered, and requires an intelligent reader to decipher the hints and allusions that Ford places throughout the text. Those who want active, clearly described plots should look elsewhere - but those who prefer not to be condescended to and enjoy puzzling out a story would enjoy this novel.
Ford never descends to the device of having characters explain something to each other that they would obviously already know, i.e. "As you know, George, a light bulb is a luminescent device powered by electricity that creates light in dark areas." For science fiction in particular, I find this very refreshing.
Finally, Ford's teenagers are active, thinking kids with dreams and desires. If they are very bright, they also seem very real to me.
It's worth finding a copy of this book. Better still, it would be worth bringing back into print.
