Nobel Prize-winning scientist Sarah Collier has started to show the same tell-tale signs of Alzheimer´s disease as her father: memory loss, even blackouts. So she is reluctant to accept the invitation to be the guest of honour at a prestigious biotech conference - until her husband Daniel, also a neuroscientist, persuades her that the publicity storm will be worth it. The technology being unveiled at this conference could revolutionise medicine forever. More than that, it could save Sarah´s life. In Geneva, the couple are feted as stars - at least, Sarah is. But behind the five-star luxury, investors are circling, controversial blogger Terri Landau is all over the story, and Sarah´s symptoms are getting worse. As events begin to spiral out of control, Sarah can´t be sure who to trust - including herself.
