The tenth novel in the New York Times bestselling Tracers series is a gripping romantic thriller from the author who “never fails to put me on the edge of my seat” (USA TODAY). The moment detective Reed Novak steps onto the crime scene, he knows the case is going to rock his world. A beautiful young woman murdered at home. No sign of forced entry. No motive. She’s obviously not the killer’s first victim, and Reed’s instincts tell him she won’t be his last. Reed’s first clue comes via a mysterious text that links to a dating profile, but even more intriguing than the clue is the person who sent it. As a white-hat hacker in the Delphi Center’s cyber investigation unit, Laney Knox sneaks into some of the deepest, darkest corners of the Internet looking for predators. Laney would prefer to stay away from Austin PD’s most recent murder case, but she can’t ignore the chilling similarities between that crime and her own brutal attack years ago. Laney offers to help the sexy lead detective, but he wants more from her than just a promising tip—Reed wants her trust. Laney resists, but as their relationship deepens she’s tempted to reveal the closely guarded secrets that could make her a key witness…or the killer’s next victim.

This fifth thrilling Tracers novel from bestselling and award-winning author Laura Griffin features a rookie cop and an FBI profiler who discover they’re after the same killer—or is the killer after them? Rookie detective Allison Doyle only has room in her life for one goal: to prove to herself and everyone else that she is every bit as capable as the men in her small-town Texas police department. But when vicious murder sends a shock wave through her community, Allison finds herself at the epicenter of a bigger challenge than she ever imagined. Legendary FBI profiler Mark Wolfe arrives to consult on the case and puts forth a startling new theory—that the crime is the handiwork not of the police’s prime suspect, but of an elusive psychopath Mark has been hunting for more than a decade. Facing skepticism from local investigators, Mark casts about for someone open-minded enough to listen to his theory—and zeroes in on Allison. Teaming up with Mark puts Allison’s professional reputation in jeopardy—not to mention her heart—but she shoves these risks aside so she can tap into one of the FBI’s best assets. With Mark’s help, as well as an elite group of forensic scientists known as Tracers, Allison uncovers the killer’s true identity. Or does she? As the net tightens around a psychopath, Allison begins to wonder if she and Mark have trapped a killer or become ensnared.

From the award-winning author of Sandworm comes the propulsive story of a new breed of investigators who have cracked the Bitcoin blockchain, exposing once-anonymous realms of money, drugs, and violence. “I love the book… It reads like a thriller… These stories are amazing.” (Michael Lewis) Over the last decade, a single innovation has massively fueled digital black markets: cryptocurrency. Crime lords inhabiting lawless corners of the internet have operated more freely—whether in drug dealing, money laundering, or human trafficking—than their analog counterparts could have ever dreamed of. By transacting not in dollars or pounds but in currencies with anonymous ledgers, overseen by no government, beholden to no bankers, these black marketeers have sought to rob law enforcement of their chief method of cracking down on illicit finance: following the money. But what if the centerpiece of this dark economy held a secret, fatal flaw? What if their currency wasn’t so cryptic after all? An investigator using the right mixture of technical wizardry, financial forensics, and old-fashioned persistence could uncover an entire world of wrongdoing. Tracers in the Dark is a story of crime and pursuit unlike any other. With unprecedented access to the major players in federal law enforcement and private industry, veteran cybersecurity reporter Andy Greenberg tells an astonishing saga of criminal empires built and destroyed. He introduces an IRS agent with a defiant streak, a Bitcoin-tracing Danish entrepreneur, and a colorful ensemble of hardboiled agents and prosecutors as they delve deep into the crypto-underworld. The result is a thrilling, globe-spanning story of dirty cops, drug bazaars, trafficking rings, and the biggest takedown of an online narcotics market in the history of the Internet. Utterly of our time, Tracers in the Dark is a cat-and-mouse story and a tale of a technological one-upmanship. Filled with canny maneuvering and shocking twists, it answers a provocative question: How would some of the world’s most brazen criminals behave if they were sure they could never get caught?
