Project 13 · Two-book promotion & reader discovery
From One Book to a Growing Series: Jeanne Yliss
A continuing reader-discovery and promotional partnership for the two-book French-language series On détonne contre Huntington.
Volume 1

Volume 2

Author Growth Pro partnered with French independent author Jeanne Yliss to support the discovery and promotion of De colère et d’amour, then continued the work across the release of its sequel, Du chaos aux sommets. These emotionally driven books trace family crisis, the impact of Huntington’s disease, and a later movement toward resilience and sporting challenges.
This 2025 campaign combined audience research, keyword and Amazon listing optimization, tailored promotional activity and continuing reader-discovery support. It is one chapter in a relationship spanning multiple projects over several years—not the beginning of the entire collaboration. The approach focused on relevant French-speaking readers and communities, not a single assumed geographical market.

The original €520 fee covered the six-week Seed engagement for Book 1. Subsequent support across the series was separate from that initial scope. Later fees, payment status and private engagement terms are not part of this case study.
The client’s challenge and objectives
Jeanne wanted to reach French-speaking readers who would genuinely connect with the books’ content, characters and themes, including new readers beyond her existing audience. The aim was to create relevant opportunities for discovery and consideration—not simply expose the series to an undefined audience.
- Help Book 1 become discoverable to readers interested in psychological suspense and emotionally intense family drama.
- Research promotional pathways, relevant reader communities and book-club opportunities beyond the Amazon listing.
- Improve book positioning through relevant keyword research and Amazon listing SEO support.
- Maintain attention on the first volume while the sequel was prepared and released.
- Introduce Book 2’s distinct themes of resilience, sibling solidarity and sporting challenges, while making the series order clear.
- Support continuing publishing objectives through an ongoing, separately scoped promotional relationship.
The campaign strategy
Stage 1 — Book and audience research
Research began with Jeanne’s titles, descriptions, genre, themes and intended readership. Book 1’s psychological suspense and family conflict informed its positioning; Book 2’s resilience and sporting challenges informed the sequel’s approach. Relevant reader interests, book groups and book-club opportunities were researched for French-language discovery.
Stage 2 — Keyword research and Amazon listing optimization
Book-specific keywords, related search terms and discoverability opportunities were researched for the French-language market. Amazon listing SEO and recommendations aimed to communicate each title’s subject and appeal more clearly. Optimization was part of the work, not a promise of rankings or sales.
Stage 3 — Tailored promotion and reader discovery
Promotional messaging drew on the stories and descriptions Jeanne supplied. Reader outreach and community-oriented opportunity research focused on relevant interests and new readers beyond the existing audience, rather than broad, undefined exposure. The two titles were not treated as requiring identical messages or communities.
Stage 4 — Connecting Book 1 to Book 2
Book 1 discovery → continuing reader awareness → Book 2 awareness and release → continued support across the series. Promotional attention to the first title continued while the sequel was prepared and released, with each book retaining its own positioning.
Stage 5 — Ongoing support and refinement
The collaboration continued beyond the original six-week engagement, with further reader-discovery work, promotional opportunities, listing optimization and attention to Jeanne’s evolving publishing objectives. Later work was separately agreed, not automatically included in the original package.
Comprendre les livres, trouver les bons lecteurs
Une promotion pertinente commence par le livre lui-même. Les titres, sous-titres, descriptions, genres et thèmes communiqués par Jeanne ont servi de point de départ à la recherche. L’objectif était d’aider les lecteurs francophones à comprendre ce qui distingue chaque volume avant de décider s’il leur correspond.
Tome 1 — De colère et d’amour
Ce drame familial intense suit la famille Pouillet lorsque la maladie de Huntington bouleverse son foyer. Olivier refuse de reconnaître sa maladie ; sa colère imprévisible fragilise les liens avec sa femme et ses enfants. À treize ans, Charline découvre son père debout sur une chaise, une corde au cou. Inspiré de l’histoire vraie de cette famille, le récit montre comment une maladie héréditaire grave affecte aussi ceux qui vivent aux côtés de la personne malade.
Le positionnement s’adresse aux lecteurs francophones sensibles au suspense psychologique, aux tensions domestiques et aux drames familiaux contemporains inspirés de faits réels. La recherche et les messages promotionnels mettent en avant les relations familiales, la peur et les enjeux émotionnels du récit, afin d’identifier des occasions de découverte cohérentes avec le livre.
Tome 2 — Du chaos aux sommets
Après la séparation, chaque membre de la famille Pouillet affronte les blessures invisibles laissées par son histoire. Charline, désormais âgée de dix-huit ans, refuse de se laisser définir par l’adversité. Portée par l’héritage sportif de ses parents, elle entraîne son jeune frère dans des défis ambitieux. Ce second volume explore la résilience, la solidarité familiale, l’épuisement des aidants et le choix d’agir plutôt que de se résigner.
Le positionnement privilégie les lecteurs francophones intéressés par les récits de résilience, les relations familiales, le dépassement de soi et les défis sportifs. Les messages soulignent l’évolution de Charline et les épreuves partagées par les enfants, tout en présentant clairement ce volume comme la suite de l’histoire des Pouillet, sans supposer que chaque lecteur connaît déjà le premier tome.
Une recherche guidée par le contenu
Analyse du livre
Comprendre l’intrigue, le ton émotionnel, les thèmes et la place du livre dans la série à partir des informations fournies par l’autrice.
Positionnement des lecteurs
Identifier les centres d’intérêt liés au suspense psychologique, au drame familial, à la résilience et à la fiction contemporaine inspirée de faits réels.
Recherche approfondie de mots-clés
Étudier les termes liés aux sujets et aux genres, les intérêts de lecture comparables et les expressions de recherche pertinentes pour le marché francophone. Chaque titre a reçu une attention adaptée : une même liste de mots-clés n’a pas été appliquée indistinctement aux deux livres.
Optimisation des fiches Amazon
Soutenir le référencement et formuler des recommandations pour mieux faire correspondre la présentation et la découvrabilité de chaque livre à son contenu et à son public.
Messages promotionnels adaptés
S’appuyer sur les descriptions et les détails narratifs de Jeanne pour exprimer la tension et les liens familiaux du premier tome, puis la solidarité, les défis et le nouvel élan du second.
Découverte de nouveaux publics
Rechercher des communautés de lecteurs, des possibilités de clubs de lecture et des voies de promotion en lien avec les thèmes, pour aller au-delà du lectorat existant sans recourir uniquement à une exposition générale.
Continuité de la série
Maintenir l’attention sur le premier livre, présenter le second comme une suite et rendre l’ordre de lecture compréhensible, sans supposer que les deux titres partagent exactement les mêmes lecteurs.
Cette démarche donne un fondement concret aux décisions promotionnelles : comprendre l’histoire, rechercher les intérêts de lecture pertinents, puis traduire cette compréhension en travail de positionnement et de découverte. Les livres abordent la maladie de Huntington à travers l’expérience familiale et le récit de l’autrice ; Author Growth Pro n’intervient pas dans le domaine médical.

The author’s experience
Five-star client feedback · Jeanne Yliss · Published with permission. The testimonial reflects the ongoing relationship across multiple projects, not a claim about specific sales or ranking results.
“Working with Author Growth Pro over the years has been a valuable part of my journey as an independent author. From promoting my earlier books to supporting the release of Du chaos aux sommets, I have appreciated the continued dedication, communication, and effort put into helping readers discover my work. What I value most is the ongoing support and the understanding of my publishing goals. Our collaboration has continued across multiple projects, and I appreciate having someone who is willing to work with me as my books and readership grow. I look forward to continuing this partnership and exploring new opportunities for my future releases. Thank you to Author Growth Pro for being part of my journey as an author!”
Promotion that can grow with your catalogue
An author’s publishing journey does not always fit into a single launch window. This project demonstrates how book-specific research, optimization and promotional execution can be coordinated across related titles, with continuing attention beyond the initial engagement when further support is agreed.
Each book retains its own narrative, reader appeal and positioning while benefiting from a clear series-discovery pathway. The broader view considers how titles connect and how future releases fit an evolving catalogue, without attributing the author’s entire publishing success to one service provider.
