Blood in the Code (en Inglés) - Jason Lemaire

Willam Hill thought he understood the rules of the game-until the game changed. A skilled coder with a haunted past, Willam discovers a hidden message in the system that drags him into a deadly web of secrets, betrayal, and blood.

As the lines between digital and real-world danger blur, Willam must navigate a city where every keystroke could be his last and every ally might be a traitor. With a past he can't escape and enemies he can't see, survival becomes more than a choice-it's a code he must crack... before the code cracks him.

Blood in the Code is a gripping, fast-paced thriller that will keep you on the edge of your seat until the very last page.
