Editing Between Planets (section)

==Plot summary==
Don Harvey's scientist parents withdraw him from his [[secondary school|high school]] in [[New Mexico]] in the middle of the term so that he can join them on [[Mars]]. The headmaster suggests that they want him out of a potential war zone, where he might be viewed suspiciously because of doubts about his loyalties. At his parents' behest, he visits an old family friend who asks him to deliver a ring to his father; security forces later arrest both of them. Harvey is released and given his ring back, after it has been examined; he is told that his friend has died of "heart failure". Only later does he realize that ''all'' deaths can be described that way.

Harvey boards a shuttle to a [[space station]] orbiting Earth. The station doubles as a [[transshipment]] terminus and a military base, armed with missiles to keep restive nations in check. On the trip up, he befriends another passenger, a [[Venus|Venerian]] "dragon" calling himself "Sir Isaac Newton". Sir Isaac, a renowned physicist, can vocalize English using a portable device.

Harvey gets caught up in the Venerian war of independence when colonial forces capture the station in a surprise raid. Most of the other travelers are sent back to Earth, while a few decide to join the rebels. Harvey is in a quandary. The spaceship to Mars has been confiscated, but he remains determined to get there, by way of Venus if necessary. Because he was born in space, with one parent from Venus and the other from Earth, he claims Venerian citizenship; more importantly, Sir Isaac vouches for him. He is allowed to tag along, which turns out to be very fortunate for Harvey. The rebels blow up the station to stir up trouble for the Earth government. When the shuttle returns to Earth with its radios disabled, the military assumes it has been booby-trapped and destroys it, killing all aboard.

On his arrival on Venus, Harvey finds that his Earth-backed money is now worthless. A banker lends him money, telling him to [[pay it forward]]. He gets a job washing dishes for his keep for Charlie, a Chinese immigrant who runs a small restaurant. He befriends a young woman, Isobel, when he tries to send a message to his parents. However, communication with Mars has been cut due to the hostilities. Harvey settles in to wait out the war, but the war comes to him.

Earth sends a force to put down the rebellion on Venus. The Venerian ships are destroyed in orbit and the ground forces are routed. Charlie is killed resisting the occupying soldiers. Harvey is rounded up and questioned by a senior security officer, who is very eager to get his hands on Harvey's ring. Luckily, Harvey had given it to Isobel for safekeeping; he does not know where she is or whether she is even alive. Before he can be interrogated with drugs, he escapes and joins the Venerian guerrilla forces.

Harvey joins the army of the Republic and becomes an effective commando. In time, he is tracked down by the leaders of the resistance, who are also looking for the ring. Isobel and her father (an important member of the rebels) are safe at the very base where Harvey is taken.

The seemingly valueless ring turns out to contain the secret of scientific breakthroughs resulting from archaeological studies of an extinct alien civilization on Mars. With Sir Isaac's assistance, the rebels use the information to build an advanced spaceship that is much faster than any other vessel in existence, with revolutionary weapons and defenses also derived from the new technology. As a combat veteran, Harvey is recruited for the maiden voyage of ''Little David'', manning a [[dead man's switch]] with strict orders to blow up the ship if it is in danger of capture. ''Little David'' intercepts and defeats a task force of warships on their way to Mars to crush the revolt there.
