When the Rules That Govern Men Are Shattered,
All You Can Trust Are the Invisible Rules
That Govern Life Itself
For math prodigy Leonhard Euler, the Bernoulli family have been more than just friends. Master Johann has been a demanding mentor, and his sons have been Leonhard's allies and companions. But this is a family torn by jealousy. Father and sons are engaged in a ruthless competition for prestige among the mathematical elites of Europe. And now, their aspirations may have turned deadly.
Lured into an investigation of the suspicious death of Jacob Bernoulli, his master's brother, twenty years ago, Leonhard soon discovers he's facing an elusive puzzle as complicated as any math equation. Surrounded by the world's most brilliant--and cunning--minds, Leonhard finds himself tracing an unraveling and invisible spiral of greed, blackmail, and murder. He'll need all his genius to find an elegant solution to this desperate battle of wills.
