Summary: Tormented by memories of past lives and a general distaste for structure, Sloane dropped out of a prestigious magic college to find themself. During their travels, they came across a curious little creature: a chatty spider that fit snugly in their hands. Unbeknownst to Sloane, this wasn’t a harmless garden or cellar spider. The spider had a thirst that mere flies couldn’t quench. It demanded blood and flesh, and when mice failed to suffice, moved on to bigger and dangerous prey. Sloane appeased it as best they could, but as the spider rapidly shot up in size, turned their focus from butcher shops to farms. Together, they concocted a plan to “solve” a manifested loss of cattle. The spider got a steady supply of food, and Sloane got street cred as a “monster slayer”. “What could possibly go wrong?” – Famous last words of any irresponsible pet owner. So now Sloane has a very real infestation to contend with, along with suspicious rangers and wannabe hunters edging in on their turf. “…I’m gonna need a bigger boot.”

Summary: A remote resource planet. A mysterious illness. And a rescue team frighteningly out of their depth. It was supposed to have been an easy job: go in, kidnap or kill his mark, get out. Shine's done plenty of jobs like this before, no problem. But when it all goes suddenly wrong, he has only one option left to save his skin. He finds himself an unwilling volunteer on a medical mission to a remote resource planet. It sent in a distress call a week earlier, and then promptly went silent. No one knows why, and no one can contact them to find out. And, Shine is increasingly beginning to realize, every person on this mission is politically unimportant--a perfect crew of disposables. Their mission is to go in and figure out what happened, and save whoever they can. But he's smart enough to realize that anything that could cause an entire mining colony to go silent is probably not something accustomed to leaving its victims alive. And after meeting the rest of the crew, he's not sure that they're any safer than what's waiting for him out on the planet ... Set in the world of The Devil and the Dark, Inhuman is the first book in R.M. Olson's gripping new space-horror series, The Dark Between Stars.

Summary: A long-dead genius. A hidden invention that could save—or doom—humanity. Can Leif find it before it falls into the wrong hands? The Martian Girl is a myth, some people say, created in the dark years after an apocalyptic global war. Perhaps she was a genius in mathematics and the greatest theoretical physicist since Einstein and Hawking. She may have made a mathematical breakthrough or a powerful weapon. No one knows for sure. In AD 2726, Leif Grettison, former army ranger and exoplanetary scout, returns from the stars a weary man. Four and a half centuries have passed since he was last on Earth. Now, statues honor him, and history books extol the almost-accurate legends of Lucky Leif. But all he really wants is a small cottage on a hill with a good view and no neighbors. (Good luck with that, Leif!) Leif knows nothing about the Martian Girl. But when he agrees to a simple request, his path leads to a relationship he never expected, two teens nobody wants, and a scheme to revive the Martian Girl’s former home, a dead city on Mars. Suddenly, discovering what the Martian Girl did is the center of Leif’s life. Bringing a city on Mars back to life is hard enough, but some of the team are agents of competing powers, each determined to find what the Martian Girl created. They will resort to anything, even murder, to possess it. If there is a weapon and Leif cannot secure it, his friends will be in danger, the shaky peace on Earth will collapse, and the world may plunge into devastating wars. Can a legend still gripped by his past save our future? Or will the Martian Girl’s invention push humanity over the brink?

Summary: Another spaceship, another explosion. Harold Galahad would love to wake from this particular nightmare that is so eerily similar to the events that cost him his beloved wife and destroyed his soul. But the only way out is by saving the ship and its entire crew. If you ask Harold Galahad, he isn’t fit to lead a crew or command a ship. But nobody is asking Harry. Instead, he finds himself back on the bridge, on a ship stranded in space, no help in sight, only kept alive by remnants of a gradually failing life support system. His crew? A nurse running out of tentacles and eyes to care for all the wounded, a chief engineer who knows all about her systems but struggles with people, a chief of security who thinks everything can be solved with paragraphs from the Company’s handbook, a cursing chief of logistics, an anxiety-ridden communications officer, and a first officer who stays mysterious and feigns ignorance. This ship needs a captain to avert a complete disaster that includes the death of everyone on board. Can Galahad overcome his trauma? Can he find solutions where there are none? And worst of all, can he unravel all the mysteries surrounding the ship, its crew and the system they all work for? If you enjoy a complex tale that brings a human element to all species that travel space, combined with a multi-layered mystery, and starring a broken hero, Herald Petrel by Strange Seawolf will deliver. Warning: contains adult language and a considerable amount of swearing -- it is a cargo space ship in a desperate situation, after all.

Summary: It’s the summer of 1971, and all ten-year-old Janina Starcevich wants to do is spend the seemingly endless warm days riding her bicycle, climbing trees, and catching frogs in the pond in her back yard. But when a young drifter named Justin Lazarus walks into the hardware store owned by her next-door neighbor, Kathy Christian, a series of events are set in motion that will change them all forever. Justin is a melding of opposites—charming but odd, friendly but frightening, seemingly ordinary but at the same time deeply strange. Kathy compares him to an optical illusion before you’ve figured it out. Something’s wrong, but it’s impossible to say exactly what. The events of that sweltering summer turn the little village of Guildford, New York upside down. So why, twenty-five years later, can Janina—now happily married, with three children of her own—barely remember what happened? A chance mention at work starts her on an obsessive quest to reconstruct how the tragedy in 1971 unfolded, and to try to figure out what had been her role in it. The more she uncovers, the more puzzling and disturbing it becomes—an enigma that has lain buried for two and a half decades, centering around one single question: Who was Justin Lazarus?

Summary: Perry's mother told him he'd develop the superpower of flight, like his grandfather. She even named him Peregrine, so folks would call him "The Falcon." Spoiler— they don't. Because when he did come into his power, all he got was the ability to change colors. Not even himself, like some kind of Chameleon Man, but the color of objects. He can de-pukify the shade of his bedroom curtains, turn a bully's sweatshirt pink, or even turn a red traffic light green. (Not a good idea.) He hasn't told anyone except his disappointed mom about his power. What would they call him? The Interior Decorator? Back in high school, under stress, he did convince his power that transparent was just another color. Now that ability's sometimes fun in an illicit way. Then one morning, in the mailroom at work, he turns a cardboard box transparent and sees a bomb inside. And Perry's ordinary life explodes. Sergeant Deckard of the Nova City Bomb Squad never thought much about superheroes, or supervillains for that matter. He has plenty of work with ordinary humans and their explosives. Until he and his bomb-sniffing dog, Nix, get called to a possible-explosives situation in a highrise mailroom. The guy who reported the bomb is a nerdy twink in dark-framed glasses who pushes all of Deck's buttons. When he finds out the young man has a weird superpower and may be the target of a villain, every protective instinct comes into play. Deckard's goal is to keep his job, his dog, Nova City, and Perry intact. His libido can just sit down, shut up, and take a number. But as their attraction gets hotter and the villain closes in, their future might be blown apart before it even has a chance to start. Transparent Is a Color is a part of the multi-author Subpar Superheroes MM romance series. (Content warning for abduction, parental emotional abuse)
