Gwendy's Final Task - Stephen King (2022)

Gwendy’s Final Task by Stephen King and Richard Chizmar, published in 2022, is the third installment in the Gwendy’s Button Box trilogy. The story follows Gwendy Peterson, now a U.S. Senator, as she embarks on a perilous space mission carrying the infamous button box – a mysterious and dangerous artifact capable of great destruction. With her mind deteriorating due to early-onset Alzheimer’s, Gwendy must complete a final, crucial task before the box falls into the wrong hands, all while confronting the weight of her past and the fate of the world.

Plot Summary

A heavy silence fills the spacecraft as Gwendy Peterson straps herself in, gripping the small white case between her knees. At sixty-four, she has spent a lifetime carrying the burden of the button box, an object of immense power and unfathomable danger. The case, stamped with CLASSIFIED MATERIAL, contains the mahogany box that once appeared in her hands as a child and again as a young woman. Now, she is on a mission to rid the world of it forever, a mission that takes her far beyond the bounds of Earth itself.

The launch is brutal. The engines roar beneath her, shaking the cabin, pressing her into her seat with a force that makes breathing feel like a luxury. The other crew members – scientists, military personnel, and one billionaire playboy – endure the same crushing force, but none of them carry a burden quite like hers. The button box has followed her through the years, tempting her with its simple yet terrifying power. A single push could change the world. A single mistake could end it.

As Eagle-19 Heavy breaks through the atmosphere, weightlessness sets in, and for a moment, she lets herself marvel at the way the Earth falls away beneath them. Blue and green and impossibly vast, spinning in the void. A beautiful, fragile thing. It is for this world that she is doing this – because she knows, with certainty, that as long as the button box remains on Earth, someone will find it, someone will use it. It must be cast into the void, sent where no human hands can ever reach it again.

The mission is officially for science – a routine trip to Many Flags, the orbital station where international researchers gather to study life beyond Earth. But Gwendy’s purpose is different. Hidden beneath her title as a U.S. Senator is the true reason she was chosen for this flight. She is the only one who understands the magnitude of what she carries. But there is another threat aboard the ship, one that breathes and watches and waits – Gareth Winston, a billionaire with too much curiosity and too little restraint.

Winston suspects. He has seen the case, the way she guards it, the tension in her shoulders every time he is near. He jokes, he pries, he tries to tempt her into revealing its contents. But Gwendy has been in politics long enough to know how to handle men like him. She smiles, deflects, and holds on tighter.

She has more than Winston to worry about. The fog of forgetting drifts into her thoughts, uninvited and unrelenting. She loses words, forgets names, stares at familiar faces and finds them unfamiliar. Early-onset Alzheimer’s is eroding her mind, piece by piece. She has written the access code for the steel case in her notebook, boxed it in red ink, but what if she forgets why she needs it? What if she forgets what she came here to do?

Days pass in the station, routines blending together. She records climate data, follows protocol, pretends that she is just another passenger on this journey. But she is running out of time. The moment to act is near, and the presence of the button box calls to her, whispering possibilities, tempting her with the past.

She has seen what it can do. She has seen the dark hunger it plants in people, the way it lingers in the mind even after it is gone. In her youth, she resisted it. She made the choice to lock it away. But time and memory are slipping, and the weight of the task ahead is growing unbearable.

Then, an unexpected complication – Winston acts. He has been watching, waiting for his moment. He steals the case, retreating to his private cabin, convinced that whatever is inside must be worth billions. When Gwendy realizes, panic grips her. If he opens it, if he finds the box, if he presses one of those buttons thinking it will bring him wealth or power, then everything will be lost.

She follows him, floating through the zero-gravity corridors with urgent, practiced movements. She finds him struggling with the locks, cursing as he attempts to force the case open. When she enters, he grins, as if he has won, as if she is powerless to stop him.

But Gwendy is not powerless. She has carried this weight for too long, lived too many years with the knowledge of what this box can do. She does not hesitate. In the weightlessness of space, she propels herself forward, slamming Winston into the wall. The force is just enough. The case drifts from his hands, spinning lazily, and she catches it, clutching it against her chest.

He shouts, demands, threatens. But she is done listening.

With the case secured, she makes her way to the airlock. This is the moment she has been waiting for. The others are preoccupied, unaware of the true nature of her mission. She inputs the code, unlocks the steel case, and for the last time, she lays eyes on the mahogany box. It looks so harmless, sitting there, waiting. The buttons gleam. The temptation lingers.

She could end all suffering. She could reshape the world. She could cure her own mind.

She grips the box with steady hands, forces her thoughts into focus.

No.

With careful precision, she seals the box in a containment unit, presses the controls, and watches as the airlock releases. The hatch opens, and with one final push, she sends it into the void. The button box, the burden, the temptation – all of it drifts away, spinning into the endless dark.

It is done.

She waits, half-expecting some cosmic force to intervene, for the box to find its way back. But space is vast and uncaring. The box shrinks, disappears, becomes nothing more than a speck before it is gone.

A great weight lifts from her shoulders. The world – her world – is safe.

But inside, she knows another battle remains. The one within her own mind.

She returns to the crew, to the station, to the ordinary tasks of survival in space. No one knows what she has done. No one will ever know.

As she looks out the porthole, staring at the Earth below, she allows herself a small, weary smile. The memories may fade, her mind may betray her, but this – this she will hold onto for as long as she can.

For as long as she has left.
