CHAIR TENDRE

A child vanishes. Not by chance.

"Humanity tips over in silence. When childhood becomes a strategic stake. When progress justifies the irreparable."

Claire Vale, a thirty-eight-year-old architect, sees her life collapse when her five-year-old son Hugo vanishes from Letná park in Prague. Investigators quickly reveal a chilling truth: Hugo wasn't taken by an ordinary criminal. He was selected.

Behind reassuring protocols and polished scientific speeches, the Kellner Institute advances behind a mask. It doesn't shout. It doesn't strike. It signs documents. Children with exceptional abilities are subjected to experiments aimed at creating "the next step of human evolution".

To find her son, Claire will have to infiltrate a system that justifies the irreparable in the name of progress. But the deeper she sinks into this world, the more the line between saving her child and becoming complicit in a crime against humanity fades.

"This novel doesn't seek to reassure. It questions, unsettles, and will stay with you long after you turn the last page."

Excerpts from the novel

Chapitre 1
Le Parc de Letná
Prague, 12 octobre 2024, 15h27

Le soleil d'octobre déposait sur Prague une lumière dorée qui semblait tenir à un fil. Les marronniers du parc de Letná, parés de cuivre, de rouille et d'or, crissaient sous les pas des promeneurs.

Claire Vale, trente-huit ans, architecte de métier et mère par vocation, était assise sur un banc de bois patiné. Sur ses genoux, un recueil de poésie tchèque restait ouvert à la même page depuis vingt minutes. Ses yeux gris-vert ne quittaient pas son fils Hugo, cinq ans, qui courait sur l'herbe devant elle.

Hugo, cheveux blonds ébouriffés et yeux trop grands pour son visage, serrait contre lui Bobo, un lapin en peluche bleu délavé par trop de câlins.
— Regarde, Maman ! Je suis le capitaine ! cria Hugo en brandissant une branche en guise d'épée.

Elle consulta son téléphone : 15h42. Un message de son associé. Rien d'urgent. Elle répondit rapidement, releva les yeux…

La balançoire rouge se balançait, vide. Hugo n'y était plus.

Chapitre 3
L'Institut
Institut Kellner, périphérie de Prague

L'Institut Kellner se dressait à quarante kilomètres au sud-est de Prague, dans une zone industrielle reconvertie. Le bâtiment lui-même était un paradoxe architectural : une façade ultramoderne de verre et d'acier dissimulant des structures plus anciennes, comme si l'on avait greffé le futur sur les vestiges du passé.

Le Dr Kellner n'utilisait plus les stores. Il préférait zoomer via le TPIP intégré à la baie vitrée, recoupant les flux de caméras intérieures et les données biométriques en temps réel. Ce matin-là, le rythme cardiaque du nouveau pensionnaire oscillait entre 82 et 89 : bien trop stable pour être honnête.

Puis il le vit. Un petit garçon blond, cinq ans peut-être, marchant entre les deux hommes en blouse blanche. Il serrait contre sa poitrine un nouveau doudou — pas le lapin bleu laissé dans le parc pour brouiller les pistes.
Chapitre 15
La Vérité
Un moment de révélation

— Vous voulez dire que tout ça... c'est légal ? demanda Claire, la voix tremblante.

Kellner se pencha légèrement en avant, les mains jointes sur son bureau.
— Madame Vale, la légalité est une construction sociale. Ce que nous faisons ici transcende ces catégories. Nous travaillons à la survie de l'espèce humaine.

— En les torturant ?
— En les préparant. Les capacités que nous développons chez eux ne sont pas une torture, madame Vale. C'est une chance.

Claire sentit la nausée monter. Elle repensa à Hugo, à ses yeux innocents, à sa façon de serrer Bobo contre lui quand il avait peur.

— Mon fils n'est pas une expérience, dit-elle d'une voix blanche. C'est un enfant. Et je vais le récupérer.

Reader reviews

"An absolutely gripping thriller. The plot is perfectly built and the ethical questions raised are deeply unsettling. A remarkable debut novel."

LES INVISIBLES

Those we don't see are often the ones who see everything.

"There are people whom society has decided don't count. People who, for that very reason, can go anywhere."

In the margins of big cities, there exists a ghost population — those no one really looks at. The homeless, the delivery riders, the cleaning staff. The Invisibles.

When a series of murders strikes Paris following an impenetrable logic, the crime squad faces a blind spot: the killer moves through spaces the cameras don't cover, takes corridors no one watches, vanishes into gaps known only to those who live outside the system.

For Inspector Nadia Ferrer, solving the case will demand the unthinkable: diving into this parallel world, understanding its codes, and trusting those everyone ignores.

But in that world, the line between witness, accomplice and target can shift overnight.

"Les Invisibles poses a question our era prefers to avoid: what do we really see when we choose not to look?"

THE KELLNER PROTOCOL

A child doesn't disappear by accident.

"Science doesn't take children. It selects them."

Chair Tendre — translated and adapted for an international readership. The same chilling story, the same moral vertigo, now in English for global distribution via Amazon KDP.

Claire Vale, a French architect in Prague, watches her five-year-old son Hugo vanish from a park. The police quickly reveal a disturbing truth: Hugo wasn't taken by an ordinary criminal. He was chosen.

Behind sanitized protocols and measured scientific language, the Kellner Institute operates in the open. It doesn't need to hide. It has licenses, grants, and government signatures. And somewhere inside its glass-and-steel walls, Hugo is being prepared for something that cannot be undone.

A propulsive thriller that asks the one question our era would rather not face: how far will we go in the name of human progress?

"A genuinely unsettling debut — taut, intelligent, and disturbingly plausible."

Nutrition at Every Age

0 to 100 — The nutrition bible by age

"We are not meant to eat the same thing at 2, 35 and 80. Nutrition follows our biological evolution."

After years of research and fieldwork, Patrick Zbardi delivers a reference work here: the first nutrition bible adapted to every age of life, from birth to old age.

Neither miracle diet nor contradictory advice: Nutrition at Every Age offers a scientific, accessible approach grounded in human biology. Our nutritional needs evolve with our hormones, microbiome and activity — and our diet should too.

The book covers the entire life cycle with concrete recommendations, practical guides, age-band fact sheets, and a rigorous scientific bibliography. A resource built to last — the companion of a lifetime.

Ce livre est aussi la base scientifique de l'application nutrition-evolutive.fr : deux formats, une même philosophie.

"Nutrition is not a static discipline. It's a continuous conversation between what you are, what you eat, and who you become."
