From Chris Rylander, author of the breakout hit the Fourth Stall saga, comes the second book in the Codename Conspiracy series, a funny and clever mash-up of middle grade school story and spy adventure. Ever since Carson Fender was let go by the secret agency that had enlisted his services to help foil a nefarious plot perpetrated by one of their former agents, he's been back to hanging with his friends, pulling pranks, and not having to lie to everyone about how he's spending his days. And that's for the best, isn't it? Of course, this was all before a note showed up in his school lunch, informing him that Agent Nineteen had three days left to live, and that there might still be someone inside the Agency working against them. Carson has always been able to rely on his friends—but what happens when there's no one left to trust?

NEW YORK TIMES BESTSELLER “First-rate suspense.”—People Twenty years ago, top agents from the CIA and KGB banded together to bring down the Matarese Circle, an international cabal of power brokers and assassins whose sole objective was to achieve worldwide economic domination. Now the bloody Matarese dynasty is back—and the only man with the power to stop it may have already run out of time. CIA case officer Cameron Pryce is hot on the trail of the new Matarese alliance. His only chance to terminate its ruthless activities is to follow the trail of blood money and stone-cold killers right to the heart of its deadly conspiracy. From the Hamptons to London’s Belgrave Square, Matarese assassins have already struck with brutal efficiency, eliminating all who stand in their way. Their chain of violence is impossible to stop—until Pryce gets a rare break. One of the Matarese’s victims survives long enough to whisper dying words that will blow the case wide open: the top secret code name for legendary retired CIA agent Brandon Scofield—the only man who has ever infiltrated the Matarese inner circle and lived to tell about it. “Welcome to Robert Ludlum’s world . . . fast pacing, tight plotting, international intrigue.”—The Plain Dealer

“A genre-defying blend of crime writing and science fiction.”—Alexandra Alter, The New York Times Detective Hank Palace returns in the second in the speculative mystery trilogy set on the brink of the apocalypse. There are just 77 days before a deadly asteroid collides with Earth, and Detective Palace is out of a job. With the Concord police force operating under the auspices of the U.S. Justice Department, Hank's days of solving crimes are over...until a woman from his past begs for help finding her missing husband. Brett Cavatone disappeared without a trace—an easy feat in a world with no phones, no cars, and no way to tell whether someone’s gone “bucket list” or just gone. With society falling to shambles, Hank pieces together what few clues he can, on a search that leads him from a college-campus-turned-anarchist-encampment to a crumbling coastal landscape where anti-immigrant militia fend off “impact zone” refugees. Countdown City presents another fascinating mystery set on brink of an apocalypse--and once again, Hank Palace confronts questions way beyond "whodunit." What do we as human beings owe to one another? And what does it mean to be civilized when civilization is collapsing all around you?

From Chris Rylander, author of the breakout hit Fourth Stall saga, comes an incredibly funny and clever mash-up of middle grade school story and spy adventure. There are places in the world where heroes are born. There are places where brave men and women fight a never-ending battle against evil in order to keep our country and all other countries safe. There are places where the fate of our planet is being decided, even at this very moment, the consequences of which will echo through history. None of these places is in North Dakota. Carson Fender, seventh grader and notorious prankster, knows this. He's lived in North Dakota for his entire life, going to the same boring school every day, the same boring movie theater every week, the same boring state fair every year. Nothing ever changes, and nothing ever happens. That is, until today. Because today a desperate man hands him a package with a dire set of instructions. And that package is going to lead Carson to discover that there's a secret government agency operating in his small, quiet North Dakota hometown. And that this agency needs his help.
