The Bonheur Connection (Book 27). Genevieve Lenard, #27

A rediscovered masterpiece. A lethal legacy. A manipulated blockchain. At the exclusive opening of an art exhibition, Doctor Genevieve Lenard notices something amiss with a masterpiece hailed as the rediscovery of the decade. Her life partner and the team's art expert, Colin, confirms her suspicion, yet the documentation is flawless. Caught between indisputable proof of authenticity and her own piercing perception, Genevieve faces a cognitive dissonance that is more than just a puzzle to her neurodivergent mind-it is a source of profound distress.
What initially appears to be a simple case of confirming provenance quickly morphs into a high-tech nightmare. Navigating the uber-rich of Europe and digital subterfuge, Genevieve and her team walk a razor-thin line between truth and trust as they face an adversary who wields technology like a weapon, manipulating markets and evidence from the shadows. With the line between authentic and fake blurring by the second, Genevieve must stop a hacker who threatens to shatter wealth across the globe and plunge the world economy into chaos-before the truth becomes impossible to prove.
