Former Marine Raider Max Ahlgren is on a perilous mission for the FBI. He might not live to collect his payment....

After enduring a hellish ordeal in South America, Max Ahlgren is on the hunt for one of the men who murdered his family. Desperate for leads, he enlists the help of an old friend from the Corps who is now with the FBI. But the favor doesn't come cheap - in return, Max is tasked with helping a fierce yet inexperienced female FBI agent escort a brilliant computer programmer, his young son, and his AI software Nexus safely across the country. Nexus is the most advanced AI processor in the world, able to access any computer network, no matter how secure.

But delivering Nexus may be more dangerous than Max ever imagined. From the neon streets of Vegas to the crumbling facade of Washington DC, Max's cunning and combat skills are put to the test by foreign agents, contract killers, and rogue operatives who will stop at nothing to steal the technology. He doesn't have a choice. Nexus is the key to unlocking his dark past and bringing his own brand of justice to his family's killers.

They want Nexus. Max is going to give them a war.

Max Ahlgren returns in the internationally best-selling Crucible series. A must-listen for science fiction and thriller fans alike, NEXUS is a runaway freight train of action and suspense!
