Johnny and the Bomb – Terry Pratchett (1996)

Johnny and the Bomb by Terry Pratchett, published in 1996, is part of the Johnny Maxwell trilogy, a young adult science fiction series renowned for its wit, depth, and Pratchett’s signature satirical edge. In this installment, Johnny and his misfit friends stumble upon time travel via the eccentric Mrs. Tachyon’s mysterious shopping cart, leading them back to WWII-era Blackbury where they confront ethical dilemmas and the weight of history.

Plot Summary

It started with a cart. A rattling, squeaky-wheeled shopping cart pushed by a half-mad woman named Mrs. Tachyon, who seemed stitched together from layers of wool, old curtains, and ancient mutterings. She was a fixture of Blackbury, muttering about time and war and bananas, dragging her cart full of black bags and vinegar-scented secrets through alleyways and pavements. When Johnny Maxwell and his friends – Bigmac, Yo-less, Wobbler, and occasionally the formidable Kasandra – found her injured in the street, they did what few would have. They called an ambulance. And they took her cart.

The cart didn’t look like a time machine. But inside were things that didn’t belong. Pickles from a factory bombed decades ago. Fish and chips wrapped in a newspaper dated 1941. Johnny didn’t believe in nonsense. He worried about things like school, his mum’s smoking, and whether his thoughts were normal. But even his worrying couldn’t stretch to explanations for jars with mustard labels from a factory long buried in rubble.

The bags moved. They squelched and slithered as if alive. The garage where the cart was stored whispered like a radio between stations, full of voices that weren’t quite there. And then there was Guilty, Mrs. Tachyon’s evil-eyed cat with a limp and a vendetta against hands.

That’s when it happened. The cart, loaded with its strange cargo, shimmered oddly in the light. One moment, the gang was in present-day Blackbury; the next, they stood in the cold moonlight of 1941, their sneakers making quiet crunches on cobbles that hadn’t existed for fifty years. Mrs. Tachyon’s cart didn’t just hold rubbish and pickles – it held time itself.

Paradise Street was still there, whole and breathing. The buildings hadn’t yet been shattered by the Luftwaffe. The war posters and searchlights didn’t seem like history. They seemed real. Because they were. The town was braced for bombing, sandbags stacked high, windows painted black, soldiers crouched in cellars. The kids didn’t belong, with their strange accents, baffling clothes, and a cat that looked like it had survived three wars on its own.

The time-travel wasn’t exact. Sometimes it was a flicker, a lurch. Sometimes it dropped them in the wrong spot, or a little too early. But it didn’t matter. They had arrived. And what they did there would ripple through everything that came after.

Wobbler got left behind.

It hadn’t been the plan. But time wasn’t a polite taxi. When it moved, it didn’t wait. The others made it back to the present – dizzy, stunned, and terrified – to discover that Wobbler hadn’t returned with them. And stranger still, history had changed. Sir John, the mysterious billionaire with two goldfish named Adolf and Stalin, remembered the bombing differently. He had escaped from Paradise Street as a child, the only one who had. But now he wasn’t sure. Things shifted when Johnny’s group went back. And Sir John, who seemed oddly invested in Blackbury and Mrs. Tachyon, felt it. He remembered pickles and flames. He remembered a boy named Johnny Maxwell.

They had to go back. To find Wobbler. To put things right. To stop Paradise Street from being obliterated when it didn’t have to be. Because now they knew what would happen – the bomb would fall, the street would vanish, lives would be erased. Unless they changed it.

But time is a tangled thing. And changing the past is never neat. They tried disguises, false names, hiding in shelters. Bigmac shaved his head to blend in with wartime Britain, which only made him look more suspicious. Yo-less, always rational, found himself navigating illogical fear and suspicion in a town on edge. Kasandra, ever composed, tried to control events like a headmistress managing a school play, while Johnny listened – to ghosts, to echoes, to Mrs. Tachyon’s nonsense that wasn’t nonsense at all.

They learned that Wobbler had found a place. He’d made friends. He’d built a life. And he didn’t want to come back.

But the bombing loomed. Paradise Street was still on the list. And someone had to stop it. Johnny understood then – not just the mechanics of time, but the weight of it. It wasn’t about being clever with history. It was about responsibility. About lives.

So they made their stand. Armed with future knowledge, borrowed uniforms, and guts stitched together with string and sarcasm, the gang warned, evacuated, and tricked their way into altering destiny. Mrs. Tachyon appeared at the right time, or perhaps the wrong time, dragging her cart like a comet of chaos through the timeline. Guilty howled. The bomb fell. But not where it was meant to.

Paradise Street lived.

And so did the memory of it. Sir John watched from afar, his memories scrambled, his past reshaped. The cat survived. The cart vanished, then reappeared, squeaking into a different when. Mrs. Tachyon, once dismissed as mad, smiled a secret smile.

Back in the present, things were… different. Not just in the town, but in the kids. Johnny wasn’t just a worrier anymore. He had stood in fire and made a choice. Kasandra, for all her commands, had glimpsed a world she couldn’t control. Yo-less believed in something stranger than facts. Bigmac still scowled, but his boots stepped a little lighter.

The cart was gone. The bags had emptied. Time had twisted, and unknotted, and moved on. And somewhere in the distance, Mrs. Tachyon’s voice muttered something about bananas, trousers, and a dollypot.

It was over. But not forgotten.
