Joel Johnston is a budding young musician and the son of a Nobel-winning physicist, who gets engaged to Jinna, a fellow orphan, only to learn that she’s the grand­daugh­ter of the richest man in the Solar System. Her grand­fa­ther, The Conrad, wants him to breed more heirs. In a fit of pique at the deception, Joel goes on a bender then hops on a colony ship to a distant star. Even at rel­a­tivis­tic speeds, it’s going to be a one-way trip.

Fifty years ago, Robert Heinlein wrote a short outline for this book, then put it aside. A few years ago, Heinlein’s estate asked Spider Robinson to complete it.

Robinson has done a great job of writing another Heinlein novel, exploring one of his classic themes, a young man finding himself, and sounding very much like Heinlein himself.

Very enjoyable.
