What kind of weapon can kill without leaving a trace?

From E.M. Kelly, award-winning author of Murder By Symbols, comes Pulse Zero, a pulse-pounding crime thriller packed with relentless suspense, shocking twists, and a race against time. Blending cutting-edge science with a gripping crime thriller, Pulse Zero delivers a heart-racing investigation where every answer uncovers a deeper secret.

When a deadly attack strikes a medical facility outside Boston, every patient dies instantly except one. The lone survivor becomes the only witness to a massacre so precise that it defies explanation. The killer vanishes without a trace, leaving behind a trail of questions that points to a terrifying new form of weaponized science.

Detective Colton Baker, a sharp intuitive investigator with a knack for seeing what others overlook, is assigned the case. Joined by FBI Special Agent Catalina Diaz, a relentless investigator whose determination borders on obsession, Baker uncovers government secrets, hidden agendas, and a conspiracy buried at the highest levels, protected by those willing to kill to keep it secret.

As the investigation deepens, Baker and Diaz uncover a chilling truth: the attack was only the beginning. What happened at the medical facility was merely a test. The real target? A Boston-area stadium packed with thousands of spectators. But which one?

With powerful forces determined to bury the truth and a killer who always seems one step ahead, the pair must unravel a deadly conspiracy before time runs out. Failure wont just cost lives. It could redefine terrorism, change the future forever, and expose just how fragile life truly is.

Can Detective Baker stop the killer before they strike again?
