Bill Lerner and his father George, along with his new wife Molly and her daughter Peg, emigrate to Ganymede in this book by Robert Heinlein, to become farmers. Life is hard between learning the ecology of a new planet and disastrous earthquakes, but Bill, an eagle scout, always stands tall and faces up to life. Like most Heinlein books, this one is delightfully faithful to science (at the time of writing, anyhow) and full of realistic details - and since the details in this book are about Ganymede and new techniques of farming - things that touch the characters' lives in a meaningful way, rather than simply intersecting with them, it doesn't get as tedious as in other books when heinlein starts rambling off about ballistics and trajectories. This is one of my favourites. Not a classic, not canon, but a good read for a rainy day.
