Tunnel In the Sky

Another memorable Heinlein cover by Darrel Sweet for Tunnel in the Sky (Ballantine, 1977). The story concerns the use of teleportation technology to colonize other planets instead of spacecraft. Things get complicated when a group of young people go on a training mission to another world and the "tunnel" shuts down, stranding them in a "lord of flies" struggle.

I've always loved the SF concept of portals and teleportation, and Sweet does a great job illustrating the doorway into a beautiful but challenging new world.
