This is the last day of my "holiday" from writing - mostly spent writing - so I thought I'd take the time to share with you what must surely be the first science fiction I ever wrote, around age ten: "Kate Danube and the Mysterious Cloud". Painstakingly typed on our constantly jamming typewriter and corrected by hand. Don't ask me why my glaring authorial self-insertion picked the surname "Danube".

It opens:
"A cloud of floating dust & gas, that's all it was, now you come to think of it. Floating there in space harmlessly and peacefully, but concealing one of the most dangerous planets - Oth, the great waring (sic) planet!"
I don't know about you, but I was hooked at the word "Oth". All the names in this are great. (It's not a very mysterious cloud, is it, given they know exactly what's inside it?)
"The planet Oth had been moved - it doesn't seem possible, does it? - from its original movement around Regulus, the brightest star in the constellation Leo, by its evil head scientists a thousand million - maybe a million million - years ago. Nobody seems to know why they did such an amazing feat on such a monstrous scale."
Possibly it was because Regulus "exploded partially" or "had a spell of heatlessness". Anyway, the evil scientists "decided to get the heck out of there".
Oth declares war on Earth "for fun" and installs "an extra radar-proof cloud". Enter our heroes, Starperson Kate Danube and her "best buddy" Lindi White (my thinly disguised school friend). The cloud is evidently a Doctor Who special effect, "swirling, looping", making Kate see "tadpoles". But before we get to the action, our heroine is leaping from her "plastibed" aboard the good ship Centaur, so enthused by her Morse Code lessons that she doesn't even pause for breakfast.
"Down the corridor from us, however, trouble was brewing. Sparko, our technician, had reported seeing a strange planet on the large space visiscreen, but no-one had believed him." I have so many questions about that sentence that this posting cannot contain them. Sparko even identifies the planet: "Xerox of the Mongolduks!" I have crossed out "of the Mongolduks" in pencil. Perhaps I should have added a little Registered Trade Mark symbol.
Now a history lesson: "Xerox was the only remaining member of the 'Great waring (sic) planets of the leadership of Oth' as the others had quit when The Stellar Federation won the great war of Eros (Oth had attempted to take over an Earth-owned asteroid called Eros which could be turned into pure shool, a deadly poison) and was completely in league with the deadly planet."
Shool! I am tickled that there really is an asteroid called Eros. The influence of Patrick Moore's Atlas of the Universe is clear. So too my lifelong obsession with Ancient Egypt; the inhabitants of Xerox are "primitive in their mode of living and slightly Egyptian, but had supertechnogical weapons ready for enormous catastrophes such as their enemies in a war winning." You can't make this stuff up. Oh wait, I did.
Anyway, Starperson Kate just happens to glance out the window and clock "a huge spacecraft" heading "at enormous speeds" towards the Centaur. It traps the ship in a spacenet. The "juvenile emergency procedure" is surprising: abandon ship! Fortunately the spacesuits have "absolute years (literally!) air supply" as well as injectable food and "entertainment circuits". Kate and her class leave a "placard on the porthole" in case anyone comes looking for them.
"As far as we could see by the placard on the main porthole, everyone had escaped and were headed towards a nearby planet that circled around a star we had been passing when the spacenet hit. But none of us could see the planet, so we were stuck where to go. But just then a light of some sort, shining brightly against the dark eternity of space, zooomed (sic) around the corner of the spaceship and let out a spacenet about the size of a human. Spotting it before everyone else I leapt over (or as well as I could in the vacuum of space) and pushed Percy out of the way before it caught him in its lethal folds and dragged him in towards its evil users."
I wish to interrupt this thrilling moment to mention another of my childhood obsessions, symbols - I have evidently read up on proofreader's symbols, which are used throughout the ms. And also to point to a probable influence on the story, Trapped in Space by Jack Williamson:

Anyway, it's no use - the Xeroxans capture our heroes, thanks to the fake placard they left on the main porthole. "Oh, What klutzes we are!" cries Kate. Her class is imprisoned in a "polycaptive cell, built to hold a crew, or at least a lot of people." But then a twist! "Luckily, we were all members of the Stellar Fed. Secret Service and had good training". They use their "escape-magnets" to bend the bars of their cage and "'Bob's your uncle', as people would say in the 20th and 19th centuries."
Kate, Lindi, and Mike hide in "a large, unused closet". On arrival at Xerox (which has "a double quasar sun") they disguise themselves in some convenient guards' outfits. Their classmates are taken to the "imperial palace". Needing a crack to see what's going on inside, they use "a device in our S.S. (Secret Service) kit". The "small, green pencil-shaped rod" sends out "supersonic waves". (They refrain from vibrating the entire palace to pieces as their friends are inside.)
"'Oh queen Neptuna of Xerox, imperial ruler and demigoddess, we of your humble imperial guard have secured thirty prisoners of the planet Terra.'
'Oh Head Guard Excelpiusen, I am pleased with your work. Go now with your men to your mess chambers.'
Neptuna had spoken and her blindly loyal - nay, hypnotised, for that was how the queen evilly ruled the planet - attendant guards left the prisoners with the queen."
This surprising development is explained by a forcefield surrounding Neptuna. The influence of Terry Nation on my young mind is soon revealed: "You will become slaves on this planet in the radioactive mines of our mountain, so do not expect comfortable living quarters!" I was laughing so much I could hardly type out that last phrase.)
Our heroes follow their classmates to the mines and alert them to imminent rescue using Morse. Setting their lasers on "stun", the three eleven-year olds knock out all the guards and share a tearful reunion with their pals. They pinch their spaceship back and vamoose with the help of an anti-radar screen: "Literally, we got away scot-free."
"As we left the planet, I said, 'It's too cruel that those poor Xeroxans are so cruelly ruled over!'" This cruel situation is quickly resolved with the help of an autohypnotyser attached to an amplifier and beamed at Xerox. "... the whole planet was freed from its hypnotic slavery. Xerox was Xerox again - peaceful and helpful, after maybe as long as 45,000 years of cruel enslavement. And all by the adjusting of a knob to 'un'."
Having completed this little side quest, our heroes continue their voyage to planet Oth, which has just announced its new weapon, the "giant carboniser ray" which, the Othans boast, will "return the people on Terra to dust, from whence they came". There follows a complex chemical explanation of the ray, which involves "dehydrating or 'un-waterising'" its victims.
"Still, the mission made you terribly afraid. You might not come back alive; you might come back alive but harshly wounded, an invalid with so much life to live; but for four billion people on Terra who would die as dust if you didn't face up to your duty, you couldn't refuse that very element - your duty. Four million (sic) people pleading for you to save them - to do your civil duty and save them. I stopped thinking about it, straightened my wavering path and, with a stiff upper lip, reported to Pauline for Judo lessons."
For you see, our heroes are learning every form of fighting to take on the Othans:
"'Next lesson up - jex guns - going to jex a few Othans?'
Despite the fears that we both had, Lindi grinned. 'Plan on jexin' the lot, Kate. And you?'"
(Pauline turns out have a backstory which makes her rather more interesting than our heros: "Pauline's a Chinese spy agent for the S.F. - used to use her Judo and Karate talents in Tokyo, where, in that country of Japan opposite her own, she had been watching other spies for a planet called Oopng." Nobody ever does get jexed, alas.)
At last they're inside the "unorthodox mist" of the Mysterious Cloud.
"'You can't see the dust for the dust-cloud, eh, Kate?'
'Nor the gas for the dust. Cee-rumbs!'"
Alas, "After a while the awe left us". Kate and Lindi go for a swim, enjoy a surprise party in their honour ('Oh my gawrsh no-ooo-ooo'), receive the gold lion of bravery medal, and at long last are dispatched on their mission to plant the "cloud-bomb" which will destroy the "central-clouding machine". You see: "Most of the cloud was optically banning, that is, you couldn't see through it, but the central cloud around the actual planet stopped even radar signals so that no matter what, you couldn't find Oth." (Think about this, folks.)
Our heroes must cross the desert plains of Oth.
"'GREAT GRAVY!!!!!!'
A tribe of giant prairie dogs was heading towards us!"
Fortunately their camo allows them to dodge the dogs - the products of radioactive pollution. "...we plodded on in silence towards our largening target". Robots attack but are lasered; Kate's friend Marz climbs inside one and pretends to be bringing prisoners to the city, where they discover the king of the Othans is a froglike creature only twenty centimetres tall. "Heehohu", he laughs.
Our heroes hide in the dunes outside the city and disassemble the robot, which runs on a "sand drive", sucking in sand, passing it through a turbine to generate electricity, and then pumping it out again. They re-enter the city inside the robot, and after "ditching the robot in a ditch (a quite logical thing to do)", they use Twentieth Century slang ("GET LOST! GO ON, VAMOOSE!") to cause the guard robots to "konk out". They set their bomb, but are trapped by the recovered robots. Kate improvises a heat-ray from a torch and a magnifying glass, turning sand to glass and trapping the robots - this is stolen directly from an episode of Rod Rocket, IIRC.
In a final scene lifted very nearly word for word in places from Robot, our heroes are offered positions on the High Juvenile Council of Terra, but instead take off in their previously unsuspected time machine.
Well I defy Kim Stanley Robinson to top that.
