Robert A. Heinlein Book Club: Episode 76: Tunnel in the Sky (Part 1)

In this episode I look at the first half of Robert A. Heinlein's TUNNEL IN THE SKY. In this juvenile, Heinlein does some interesting thing with the old Malthusian over-population narrative. The first half reads a bit like a standard adventure story, though. This novel really shines in the second half.
