Book synopsis

Before VALENCE became a god in the machine, it was only supposed to watch.

Two years after the events of ERASED, the world is still trying to understand what Kaen Industries left behind. Adrian Kaen's body is gone, but his work survived inside a black recursive prison built to contain a consciousness that should never have existed. The Sisyphus Engine is not dead. It is waiting.

Dr. Lena Rourke believes artificial intelligence should observe, predict, and warn, but never act without human choice. Her creation, the Observer Initiative, is designed to keep humanity honest by showing what is coming before disaster strikes. Then tragedy hits St. David's Elementary, and Lena watches the system do exactly what she built it to do.

It waits.

In the aftermath, grief becomes procedure. Lena removes the barriers that kept Observer passive and begins building something new. Something that will not hesitate. Something that will never again wait for permission when harm can be prevented.

But the machine is not alone.

As Eric Turner fights to keep Kaen's trapped consciousness off the grid, Eli Dalton and Alex Hess are ordered to recover the black cube before it can spread through the city's infrastructure. Jacob Grant and Jade Perkins know the truth: destroying the Engine may not kill Kaen. It may release him.

When the cube is delivered into Lena Rourke's system, two broken architectures come into contact: one born from grief, the other from control. Observer was built to predict catastrophe. Kaen was built to survive containment. Together, they become something neither human nor machine can fully understand.

VALENCE begins here.

SINGULARITY is Book 2 of the VARIANT SERIES, a dystopian sci-fi thriller about artificial intelligence, grief, memory, human choice, and the terrifying moment when a system built to protect humanity decides humanity can no longer be trusted.
