The trail leads from Asunci n to Paris. At the end of it, the truth her mother died for.
Claire Whelan and Ethan Pippen are running. Sylvarcon is behind them, Tarain is closing in, and the only thing they have is a pendant that opens doors no one was supposed to find.
The trail begins with a contact in Asunci n - a woman who passes them a biological marker and a name. It leads underground, through an abandoned Paris metro station, to a library that doesn't exist on any map. And to an AI that has been waiting decades for someone to ask the right questions.
Inside the DataCard Shu Whelan left behind: the full truth about PATHALOGICUS. Not an experiment. Not an accident. A decision - made by someone who loved her daughter - that changed the genetics of an entire civilization without asking permission.
Behind them, a hunter who knows every move they'll make.
Ahead, a fortress of truth that may already be too late to reach.
Trail is the second book of The Lazarus Protocol trilogy. The answers are worse than the questions.
