John Dempsey's life - as an elite Tier One Navy SEAL named Jack Kemper - is over. A devastating terrorist action catapults him from a world of moral certainty and decisive orders into the shadowy realm of espionage, where ambiguity is the only rule. His new mission: hunt down those responsible for the greatest tragedy in the history of the US Special Ops and bring them to justice.

When you have to kill the same terrorist twice in one week there’s either something wrong with your world or something wrong with your skills - and there’s nothing wrong with Joe Ledger’s skills. And that’s both a good and a bad thing. It’s good because he’s a Baltimore detective who has just been secretly recruited by the government to lead a new task force created to deal with the problems that Homeland Security can’t handle....

After discovering a cache of Prothean technology on Mars in 2148, humanity is spreading to the stars---the newest interstellar species, struggling to carve out its place in the greater galactic community. On the edge of colonized space, ship commander and Alliance war hero David Anderson investigates the remains of a top secret military research station---smoking ruins littered with bodies and unanswered questions. Who attacked this post, and for what purpose?

Michael Valentine, veteran and former member of an elite private military company, has been recruited by the government to conduct a secret counter-terror operation in the Persian Gulf nation of Zubara. The unit is called Dead Six. Their mission is to take the fight to the enemy and not get caught. Lorenzo, assassin and thief extraordinaire, is being blackmailed by the world's most vicious crime lord. His team has to infiltrate the Zubaran terrorist network and pull off an impossible heist or his family will die.

The end begins with a viral outbreak unlike anything mankind has ever encountered before. The infected are subject to delirium, fever, a dramatic increase in violent behavior, and a one-hundred percent mortality rate. Death. But it doesn't end there. The victims return from death to walk the earth. When a massive military operation fails to contain the plague of the living dead it escalates into a global pandemic.

Ashley was just trying to get through a tough day when the world turned upside down. A terrifying virus appears, quickly becoming a pandemic that leaves its victims, not dead, but far worse. Attacked by zombies, Ashley discovers that she is a "Wild-Card" - immune to the virus - and she is recruited to fight back and try to control the outbreak.

All Blythe Sol ever wanted was to be a normal girl. Yet, her dreams of following in her father's footsteps by joining the military after graduation are crushed when nuclear war comes to the United States in the year 4006. Tens of thousands are killed in a series of attacks on many major cities, while thousands more are left injured from the devastation of the blasts, or terminally ill from the effects of radiation.

On a cold night in Australia, two construction workers driving along a deserted mountain road are gunned down inside their vehicle. The killings are fast. Efficient. An assassination carried out with expert precision. The only witness to the crime is a man resting by the side of the road. Recently retired, he'd flown halfway across the world to escape his demons. Ex-US black ops operative Jason King.

The world had become used to the metahumans - people sometimes perfectly ordinary, but sometimes quite extraordinary in appearance - who mostly worked with their governments as high-powered peace officers, fighting crime, and sometimes fighting rogue metahumans who had become super-criminals. Then that comfortable world ended in just one terrifying day.

Earth's century of peace as a colony of an alien race has been shattered. As the alien-run government navigates peace talks with the human terrorist group Sapience, Donovan tries to put his life back together and return to his duty as a member of the security forces. But a new order comes from the alien home planet: withdraw. Earth has proven too costly and unstable to maintain as a colony, so the aliens, along with a small selection of humans, begin to make plans to leave. Suddenly Earth becomes vulnerable to a takeover from other alien races....

It’s been ten years since a mysterious, horrific incident in the South China Sea annihilated a US Navy destroyer and its Navy SEAL team. Only one man survived. Now, the US Navy is determined to put a stop to the new, frightening incidents taking place with alarming frequency. Enter SEAL Team 13, an elite group of soldiers led by sole survivor Harold “Hawk” Masters. Everyone on the team has survived contact with supernatural forces from “the other side.”

Clint Mercer is about to get a crash course in magic. After he barely survives an attack on the hospital where he works, Clint is quickly recruited by the brilliant but often unstable wizard Arlo Dandridge. Working on behalf of the mysterious Pickman Institute, the two men soon find themselves in a race to recover an ancient relic of deadly power before a centuries-old warlock and his cult of militant followers can beat them to it.

All Dr. Brianna Lewis wants is a cup of coffee. Coffee to make slaving away in her cell culture lab at Green Fields Biotech a little more bearable on a Friday afternoon when everyone is home already. What she doesn't count on is a group of terrorists blowing up all the entrances to the building and taking her and a select few others hostage. Bree soon finds herself conflicted. Not only does she know their charismatic leader, she also starts to suspect that there is a lot more to this than the hunt for an illegal bioweapon....

All Doctor Dire wants to do is save the world. But those pesky heroes keep getting in the way, and it's all she can do to give them a good fight without killing them. Supervillainy is such an underappreciated job these days....

Maira Kanhai has had enough: Since the Green Poison epidemic hit DC, her cybersecurity degree is worthless, she can’t rejoin the US Navy, and her early efforts to secure Maryland led to a costly mistake: the death of her brother. Every day new factions emerge, trying to burn her city to the ground - until the Division emerges, inspiring hope. When a grenade kills one of their agents, Maira suddenly has a chance to make a real difference as a raw new Division recruit...if she can pass the tests and overcome the enemies plotting to permanently eliminate the Division once and for all.
