Summary: SISTER. ASSASSIN. VESSEL. Echo Rodrigal isn't just a survivor; she's a success. But in a land where the law is there are no laws, the terms of success rest on a knife's edge, and Echo's luck is about to change. The Vindicata are one of the top vengeance crews in the Ten Realms of Interra. Their oaths to only commit crimes of justice have earned them the respect of their peers. But the Vindicata are more than a crew, they're a family. And ever since they adopted Echo, she's cared about one thing: making her family proud. For years, that's meant becoming the continent's most feared assassin. But each kill wreaks havoc on her soul, no matter how justified. Echo's unraveling fast, complicated by the mysterious rift growing between her and her beloved sister. Miyala's keeping dangerous secrets, and Echo cannot find the key to unlock her sister's trust. When the Warlord orders the Vindicata to transport foreign dissidents to a new prison, they must put their personal issues aside to face an impossible choice: die for defying orders, or die for breaking their oaths to uphold justice. Between meddling gods returning to the continent, mercenaries around every corner, and an ancient prophecy that foretells the end of all worlds, the pressure on Echo is mounting fast. Can she make enough right moves to save her family? The fate of many worlds rests in Echo's next choice.

Summary: In Unsafe Words, the first full-length collection of her edgy, award-winning short stories, Loren Rhoads punctures the boundaries between horror, dark fantasy, and science fiction in a maelstrom of sex, drugs, and rock-n-roll.

Featuring an introduction by Lisa Morton and cover art by Lynne Hansen, these never-before-collected stories come from the magazines Cemetery Dance, Space & Time, City Slab, and Instant City, the Wily Writers podcast, and from the books Sins of the Sirens, Demon Lovers, The Haunted Mansion Project: Year Two, Tales for the Camp Fire, and more.

Summary: Rudyard Albert Goldstein, inventor of the Biomic Network Algorithm, made piece with death once in the 22nd century, but an idiot doctor hijacked his mind, placing it in the care of Nessie, an impish AI guardian. Nessie preserved him from a civilization-ending asteroid strike so that he could help his descendants survive contact with an alien species 923,000 years, four months, and three days later. Then, he died again, merged with a worm-a-pede alien male who narrowly survived fulfilling his mating duties. They expired peacefully on a cliff top, pondering the nature of existence—and the promise of abominable liaisons.   Two deaths should be quite sufficient for any genius to endure.   Somehow, Nessie resurrected him from oblivion. His descendants needed him again. New hostile aliens roamed the Earth—along with an immortal, alien-human hybrid whose agenda was unclear. Was the healthy young body Nessie had prepared for him, along with the prospect of finally discovering “the meaning of it all” enough of a bribe to risk dying a third time?   Apparently so.   Readers of Raham’s A Singular Prophecy (Biostration, 2011), and A Once-Dead Genius in the Kennel of Master Morticue Ambergrand (Penstemon Publications, 2018) will reconnect with old friends (both human and alien). But even those new to the author’s quirky sense of humor will enjoy this third and final adventure that spans the breadth of time and space.

Summary: As the epic trilogy hurtles toward its conclusion, the fight for the future isn’t over yet. It could lead to a new beginning, or it might spell the end for the last vestiges of humankind. The generation ship Forever has left Earth behind, but a piece of the old civilization lives on in the Inthworld—a virtual realm that retains memories of Earth's technological wonders and vices. A being named Lilith leads the uprising, and if she succeeds in setting its inhabitants free, they could destroy Forever. But during the generation ship's decades-long voyage, humanity has evolved. Liminals with the ability to connect with the world mind and the Inthworld provide a glimmer of hope. They'll have to face not only Lilith’s minions, but also the mistrust of their own kind and persecution from a new government as homotypicals continue to fear what they can't understand. The invasion must be stopped, the Inthworld must be healed, and the people of Forever must let go of their past and embrace what they’re meant to become.

Summary: Isolated on Mars, anyone could start going stir crazy… Katya should be on top of the world. She’s overcome a traumatic past and now she’s part of the first permanent settlement on Mars. So why do things feel so wrong? The colonists are confined to a small base on the surface of a hostile planet, so perhaps it’s only cabin fever. After all, she’s got great friends, an exciting career, and an ex-girlfriend who – she’s sure – would do anything to have her back… But with cracks appearing in the relationships between the crew and nothing but empty Martian desert beyond the safety of their domes, it’s far too easy for the mind to drift. And when it does, it can be difficult to tell what’s real, and what’s pure imagination… Past Imperfect is a short story set during Livid Skies, SI CLARKE’s second novel. It’s written for people who enjoy science fiction that challenges their preconceptions. This is a work of neurodiverse, culturally diverse, gender-bendy, socio-politico-economic, drunken-arguments-in-the-pub science fiction – not bang-bang-pew-pew science fiction.
