The 2025 edition of Alerte in Paris (Alert at the Élysée), the second volume of the Submarine Wars saga, continues the story begun in Le piège de Noirmoutier (The Trap of Noirmoutier). After the eponymous battle, France becomes the target of a combined attack by superpowers unable to tolerate its technological supremacy in the field of weaponry. Our four heroes are then caught in an international storm where war and death seem the only outcome. This collection is followed by six volumes (translation to come) :
3. La revanche de l'ombre (The Shadow's Revenge)
4. Le feu du ciel (Fire from the Sky)
5. Ravitailleurs (Tankers)
6. Pour l'amour d'Eva (For the Love of Eva)
7. Le destin de Léa (Léa's Destiny, delayed)
8. La menace ultime (The Ultimate Threat)
All will be available on Amazon/Kindle.
