The Fold

Five people are dead. Each death looked natural — a stroke, a heart attack, dementia that moved impossibly fast. Each victim had escaped accountability for terrible things.

The deaths trace back to a six-billion-dollar supplement company whose protein-folding AI designed the perfect capsule for every customer. Then someone redesigned it to kill.

The science is real. The proteins are engineered. And Maya Castillo’s daughter just asked to try the product.

Book 2 in the Maya Castillo Series — for fans of Michael Crichton, Blake Crouch, and Robin Cook.

After reading, you'll fear:

Their supplement bottles. Personalized medicine. What's actually in that capsule.

After reading, search 'AlphaFold protein structure prediction.' The science is real.
