Summary: Finding work is easy. Staying alive is a little bit harder. When Russ Wesley finds an unusual artifact in his grandfather’s collection of rare antiquities, the last thing he expects is for it to draw the attention of a ferocious alien from a distant planet. Equally surprising is the adventurous team of intergalactic exterminators dispatched to deal with the alien threat. They’re a little wild, and a little reckless. Worse yet, they’re so impressed with Russ’s marksmanship that they insist he join their squad . . . whether he wants to or not. Blurb “This book is so much fun it ought to be illegal in all known galaxies. Ash Bishop has written a wildly imagined, deeply felt, swashbuckling page turner. I loved it.” —Jesse Kellerman, New York Times bestselling author of The Burning

Summary: This action filled, edge of your seat dystopian adventure is set in the near future, when a space probe is returning to Earth from the Cares 1 Asteroid with geological and biological samples frozen in ice for billions of years. It’s big news, the discovery of ancient organisms from an extra-terrestrial body. After the samples arrive at Interplan Astro-Research facility in the quiet city of Worcester Massachusetts, with the world’s media gathered, eager to hear official announcement that the samples are indeed biological, thus discovering evidence of complex life beyond our planet. Not everyone’s excited or happy about having alien lifeforms coming to Earth, and one group of terrorists have planted a thermobaric bomb in an elevator shaft of the facility. The bomb detonates and the facility explodes, killing hundreds of people, workers, protestors, scientists and TV crews, but far from destroying the samples, the explosion has released them from their level one quarantine and unleashes a deadly parasite that quickly infects the citizens of Worcester with infestations of strand red worms that infest the living. Despite efforts to contain the “Cares Pestis” AKA the “MR. Ripple” it spreads fast and becomes through the USA and beyond, causing a complete breakdown of society. But then comes something else, something far more menacing that threatens the very existence of human life on earth, and for Colonel Troy Glass and his fiancé Yvette, a deadly struggle for survival begins as they head west, to a secret government facility known as Haven. On their way, they pick up an eclectic group of fellow survivors, who together, battle against all the odds, both human and alien…

Summary: Royal Orders is Book 3 of the Suicide Arc. This time, it's Mitsuko Yamato-Windsor's turn in the spotlight. Since leaving the Navy, Mitsuko has become chief of King Edward's personal security, not to mention resuming her engagement. When a would-be assassin nearly kills Edward, she goes on the warpath, following a trail leading to a cult known as the Cubists. Except the founder and leader of the Cubists is no angry cleric running a jihad from the shadows. Master Ansel is, in fact, an affable space engineer who found an interesting philosophy. Someone else has coopted his legacy for violence. To find that person, he suggests she travel to sultry, war-torn Aphrodite with his most brilliant follower: Suicide. Their journey will bring them face-to-face with Gerard Kurz, a man who isn't the fanatic he seems to be. He's worse. And he plans to unleash an ancient technology. He will kidnap Suicide to bend Mitsuko to his will. Only that summons the other Children of Amargosa and the full might of the Navy. It all comes to an explosive head on the peak of Aphrodite's most sacred mountain.

Summary: Nothing is new under another sun. Not even murder. This mission should be simple. Exoplanetary scout Leif Grettison and ace pilot Yang Yong are off to deliver a load of supplies and reinforcing settlers to a recently colonized planet. It’s as routine as a starflight can be. Famous last words. Something is wrong with the colonists. They are astonishingly ill-suited for the task of settling a new world. The planet, too, is a poor place to plant a town for humans. Even if everything goes right, the colony might not survive. Then one of the colonists is found dead. Murder is a possibility. Not long after, another one dies—and this time, it’s definitely murder. In a world with only two hundred people, there’s at least one killer. Meanwhile, the colony’s new leader has a plan—but Leif has doubts. Will this man save the settlement, or use his power to become a dictator? Leif and Yong’s mission is clear: they must leave the colony in shape to survive. Leif is a retired soldier, not a detective, and when it comes to investigating a crime, he doesn’t have a clue. Literally. Still, it falls to him to follow the evidence and find the killer. He also needs to deal with the leader and the leader’s plan. If Leif fails, the only mystery may be how long it will take for everyone to die.

Summary: In the interstellar kingdom of Valoris, everyone knows the royal family is watching. They can be anyone and anywhere with their shapeshifting abilities—they are Truthspoken and to be feared. Of course, that doesn't stop the high houses from trying to take them down by any means they can. Arianna is the perfect Truthspoken Heir: beautiful, intelligent, and a master of her shapeshifting craft, determined to one day rule with the same control as her father. Her dreams come crashing down, though, when she's attacked by a rogue Green Magicker at her betrothal to a rival high house prince, when it's known that magickers can't do violence. Was it treachery, was it personal, or was it something else? Arianna has been slowly getting ill for weeks, and Truthspoken don't get sick. Dressa is the second Truthspoken heir and would like to stay that way, thank you very much. She's the glittering socialite of her father's court, more loved than feared. But when her older sister falls ill and is secretly sent away from court, there's still the matter of a much needed marriage alliance with a rival high house—and an absolutely gorgeous prince, who her sister wasn't keen on marrying anyway. When her father orders her to take her sister's place until she returns—her name, her appearance, everything—can Dressa carry on the act without falling for her sister's intended bride? Paranoia around Green Magickers is growing, noble plots are closing in, and in deep space, the only aliens humans have met are showing signs of not being pacifists after all. Can the Truthspoken hold their kingdom against the coming storm when it's already crumbling from within? The Truthspoken Heir collects the first season of The Stars and Green Magics, an epic space fantasy serial set in a diverse, queernorm universe with shapeshifting royals, glittering court intrigue, and space magic!

Summary: Variant children are vanishing at an alarming rate. It will take a uniquely mismatched pair of trackers to untangle a web of conspiracy and misdirection to find them. In his isolated cabin, variant Damien Hazelwood avoids human contact as much as possible to prevent attacks of blind berserker panic. But his rare talent as a locator makes him the go-to contractor for tricky missing person's cases and when agents bring him a troubling contract involving missing variant children, he finds it impossible to refuse. Licensed tracker Blaze Emerson can't help being irritated when he's expected to follow the strange, twitchy locator's lead on his latest case. He works alone, he's damn good, and as a variant sparker, he has both the fire and the firepower to take on anything out there. Though he has to admit there's something intriguing about a man who can find people with his brain. ​ With vastly different temperaments and backgrounds, Damien and Blaze need to negotiate quickly how to work together if they're going to crack this case. Add in the sudden appearance of Blaze's outlaw ex, the perils of tracking in the wilds, and a maddening lack of discernible motive or method, and they soon find themselves in as much danger as the kids they're trying to rescue. Variant Configurations takes place in a future Earth where humanity is reclaiming its spot in a gradually healing world. This book contains mentions of past abuse, action-adventure style mayhem, and the beginning sparks of a slow burn, series-spanning relationship.
