Alien Novels : Titles in Order

Book 16
Sci-fi action meets steamy paranormal romance in the Alien novels, as Katherine “Kitty” Katt faces off against aliens, conspiracies, and deadly secrets. • “Futuristic high-jinks and gripping adventure.” —RT Reviews 

With the human population growing and alien refugees pouring in from around the galaxy, Earth is becoming too overcrowded to sustain itself—and the solar system is filling up with the alien overflow. Advanced technology from the Alpha Centauri and Vatusan systems offers one possible solution. It’s time to explore new planets and see if any uninhabited ones can be claimed.

The President and First Lady, aka Jeff and Kitty Katt-Martini, aren’t supposed to be on this mission, but what looks like a snafu during a political photo op on the newly christened Distant Voyager spaceship turns out to be a call for help from a planet that might be Earth’s salvation…or its destruction.

The discovery of a world at the opposite end of the galaxy that seems like it could be a twin to Earth creates the usual issues for Kitty & Company. It also raises questions of Z’porrah and Ancient influence—not to mention cloning, the multiverse, and, scariest of all, whether or not the Black Hole Universe Police are starting to take too much of an interest in this particular universe.

It’s a typical day of bureaucracy and stress for President and First Lady Jeff and Kitty Katt-Martini, in part because Kitty’s been tapped to represent Earth in the Galactic Council. Kitty feels that’s a bad idea, and she might be right.

When her first official TV morning show goes awry, it’s only the quick thinking of the actor determined to make the “Code Name: First Lady” movie a reality that saves the day. It also forces Kitty to work with Hollywood.

Meanwhile, the Embassy Daycare kids are all about to enter “real school”—and none of them want to go. They may have grounds to be concerned because many of the other students and their familes seem shady, and everyone seems to have an evil agenda.

Dealing with the assimilation of the aliens who have come to Earth, while fending off advances from a variety of Hollywood types, seems like Kitty’s biggest challenge. But then she and Jeff discover that Stephanie Valentino—Jeff’s niece and the true Heir Apparent to the original Mastermind—is back.

Can Jeff and Kitty thwart the most insidious attacks yet, while keeping tenuous peace on Earth and goodwill toward all sentient species going? And can they also find time to be part of the most truly terrifying organization they’ve ever encountered—the school’s parent-teacher association?
Book 14
Sci-fi action meets steamy paranormal romance in the Alien novels, as Katherine “Kitty” Katt faces off against aliens, conspiracies, and deadly secrets. • “Futuristic high-jinks and gripping adventure.” —RT Reviews

It’s a typical day of bureaucracy and stress for President and First Lady Jeff and Kitty Katt-Martini, made more stressful when alien spacecraft are spotted making a beeline for Earth, none of them from the Alpha Centauri system. 

Then a cryptic request from an old adversary pulls Kitty out of the White House and into an explosion—and an even more explosive situation. Not only is the Mastermind back in the game, influencing the Club 51 True Believers to find and destroy all Centaurion bases, but he’s also found a dangerous benefactor and created some frightening new cloning abilities.

And, just to make things a little more challenging, those alien spacecraft are coming to ask Kitty for protection, and asylum on Earth. Police stations being blown up and war helicopters in play aren’t enoughto keep Kitty down, especially when she’s got some new alien friends helping out.

But what these aliens share will rock the world—the other aliens on their way to Earth are fleeing an enemy so terrifying that even a Z’porrah ship is trying to get to Earth for safety and protection. And if Earth isn’t able to stop this threat, there may not be anything left of humanity. 

Now Kitty and Company have to figure out where the Mastermind is and stop him, before any new aliens land. And then they have to save the world from a deadly invasion. Or, as Kitty calls it, Thursday.
Book 13
Sci-fi action meets steamy paranormal romance in Gini Koch’s Alien novels, as Katherine “Kitty” Katt faces off against aliens, conspiracies, and deadly secrets. • “Futuristic high-jinks and gripping adventure.” —RT Reviews

The President and First Lady, aka Jeff and Kitty Katt-Martini, don’t get any downtime once the Mastermind has been revealed to the world. Not only do they have myriad high-level government positions to fill, but the scrutiny and pressure on this Administration has gone into overdrive.

The sudden reappearance of a long-forgotten adversary turns out to be the tip of the iceberg. New robots and androids attacking, old enemies making new alliances, and new aliens with interesting abilities almost overshadow the fact that the U.S. still has to host a peace summit at Camp David between Israel and Iraq. It’s clear that while the Mastermind may be down, there are plenty of others ready to take his place—and all that stands between them and success are Kitty and Company.

Kidnappings, rescues, creepy hideouts, a hidden black site, and a domestic dispute that could end Jeff and Kitty’s marriage are nothing compared to finding not one but two hidden labs where dangerous and deadly things are brewing.

But when the President and his entourage finally get to the peace talks, things are no better. Mossad rightly suspects something’s wrong with both their Prime Minister and the President of Iraq. A hidden in-control superbeing, an android replacement, and an army of Fem-Bots turn the peace talks into a Battle Royale that the team might not actually survive. And if they don’t make it, Earth won’t make it, either.

But no pressure.
Book 12

As Kitty can tell you, it’s not easy being the wife of the vice president—especially not when he’s an alien from the Alpha Centauri system. But she and her A-C husband, Jeff, have learned how to roll with whatever life and the bad guys throw at them—they think.

When the Alpha Centauri Planetary Council requests a visit with the president and vice president, things look politically dicey. When the most dangerous prisoners in the most secure supermax prison escape with ease, things look bad. But when the Mastermind releases a virus that kills people in a week, things go to Defcon Worse fast.

Now it’s up to Kitty to save everyone important in the U.S. government—including her mother, her husband, and herself—before the virus spreads through the rest of the country, and then the world. Plus she’s facing invisible attackers, crazed assassins, a teenager in hiding, the most dangerous train ride ever, the disappearance of her beloved flyboys, and a mysterious alien who could be an enemy or the ally she needs.

And this time, the Mastermind’s made it very personal. Either he’s going down…or Kitty is.

Life’s never easy…

The Mastermind has finally been identified, but before Jeff and Kitty Katt-Martini can take him down, they, their daughter Jamie, Charles Reynolds, Paul Gower, Christopher White, and several others are zapped out of their solar system and into another.

Landing in scattered groups on various areas of Beta Eight in the Alpha Centauri system means getting the team back together will be a major issue. But it’s only one of the challenges they’ll face. Kitty and Company have to forge alliances with the wide variety of sentient natives on the planet while plotting to create a civil war and overthrow the king—who just may be a clone of one of their bitterest enemies, Ronaldo Al Dejahl.

Of course, to do this, they have to overcome an assortment of dangerous obstacles, protect a group of refugees, take mind reading lessons, and seek out unexpected new allies as they journey to the CenterPoint of the World.

And once they reach the All Seeing Mountain, new issues and surprises await. Because there’s more than a small war going on—they’re in the midst of the Alpha Centauri Civil War!

Being the wife of the vice president isn’t easy. Especially when your talents lie in kicking butt and rocking out, rather than politics and diplomacy.

Jeff and Kitty Katt-Martini find out just how difficult it can be when Kitty accidentally offends the Australian prime minister. Now they have to smooth things over, pronto, or risk creating an international incident the worldwide anti-alien coalitions will be able to use to force Jeff to resign and the A-Cs to leave the planet.

Before Kitty can make things even worse, a cosmic congruence and a little help from some powerful beings shoves her into another world—one where she’s been married to Charles Reynolds for years and aliens don’t exist. She’s also landed in the middle of a huge conspiracy and is marked for death…but at least that’s business as usual.

Kitty’s not the only one who’s confused, because the Kitty from that world has taken her place in this one. Now Alpha Team and the Diplomatic Corps have to make sure that no one realizes there’s been a switch, while preventing World War III from happening. And they have to do it while keeping this new Kitty in line, because she has views about what to do and how to do it, and time is running out.

Can each Kitty save the day before it’s too late and then go home to her own universe? Or will one Kitty decide to keep the other’s life—forever?
