Summary: Aria Bennet’s got a foul mouth and a temper. She doesn’t need a man to save her. She just needs the University to renew her digging permit for those Chilean cenotes. According to her grandfather’s map, it was where the door, the portcullis to another reality, was. It was also the same door that Professor Straus Cruz and his family had been guarding, because behind it, a war raged between the humans and the invaders of Earth. The words “fear” and “no” are not in her vocabulary. Attraction, yup, let’s go for it, Professor. Relationships, absolutely not. She’s not a puppy, and she doesn’t need a leash. Throw her into an alternate reality with a man walking around like he’s a T-bone steak in a suit, well then, it’s time to reassess and prove herself worthy of love. WARNING: No AI, No BOT. Themes of oppression and slavery include war, hand-to-hand combat, bloodshed, intense violence, and savagery. The narrative includes death, grief, burning, perilous mind torture situations, graphic language, and sexual activities shown on the page.

Summary: Justin Earl Knight, The Founder works with his son Rodney and a gifted healer, Peter, to rebuild the Elk Creek Tribe's community from the ashes of a series of quakes that devastate their land. We first meet Justin here when his mother summons he and his five siblings to a church celebration in 2012. There, Justin recalls his past with that church and meets a fanatic who tries to take his spirit down. Justin uses the strength of his own faith to fight off a demon and then must decide whether real family has value in a world of rejection and abuse. "The First Knight Shaman" is told from Rodney Knight's view. Peter's entry into manhood is the primary focus of "The Second Book of the Knight Shamans." Here, in "The Third Book of the Knight Shamans," Justin is the focus as he works through religious fanaticism and resurgent diseases to save the small community he founded only years before the great quakes devastated the western United States. Together, they discover their best chance of survival relies on ancient spiritualism and shamanism. Then they discover the religion which had dominated their world in the centuries before the cataclysm has fallen when Peter meets a fallen archangel in his quest to get a medical doctorate in the far-off city-state of Reno. In the end, we begin to question if Rodney were truly the first Knight Shaman, or if it was Justin himself as he negotiates his own path of spirituality from amongst the religion his culture imprinted onto him.

Summary: THE CONTINUING STORY OF GIDEON SHO, L'SANA M'RAS, PRINCESS ARIZELLE AND FREDERICK THE FIRST!!! GET YOUR POST APOCALYPTIC ON!!!! (THIS IS A DIRECT CONTINUATION OF THE FIRST SERIES -- NOCTURNE) Gideon had been dreaming and dreaming and dreaming, a dream he never seemed to able to wake from. And to call it a dream was as broken a description as a child could crayon draw. A nightmare mired in the macabre was the signpost planted in the blood of its concrete. A nightmare shivving his spine and soul with every moment it crawled forward It was filled with all those he loved, calling for him, pleading, screaming, to save them, to help them and yet he could do nothing but sleep, nothing but dream, circling on repeat over and over again. And the images were a caricature of a reality cracked in madness, Shira and So'Sha, grown, blades and death in their eyes, Shadow and Moon standing on two legs, L'Sana and Ari in a cage dreaming their own dreams, chained in their own devils, flashing images of a universe at war with itself, the Shadowborn whispering again and again 'Soon Gideon, soon....be ready.." He wanted to shatter his prison, wanted to howl, wanted to reach out to those that were his world, his everything but only sleep and dream, sleep and dream...the true War had come and he was drowning within his own mind, choking on the detritus of impotency, eternity in chains that didn't give a shit. "I will slaughter them all!!" Gideon would wake and people would die, a thousand times over they would die!!! He screamed this at himself, over and over, lost in the dream, in the macabre broken of breaking. It was the prayer he kept lamenting to no-one, kept spitting into the pillow of his insanity as the bars to his cage, tightened, crushing his flesh and his hope, endlessly cruel, endlessly ambivalent. He would wake, a promise, and a killer would come with him. -- Romance -- Progression -- LitRPG -- Multi-Versal Factions -- Gods -- GrimDark -- Classes, Levels, Skills, Abilities -- Dragons -- Dragonling Companion -- Horror

Summary: Ray Bradbury wrote, "...this book is wonderful!" in his review of War Eagles. A disgraced pilot, world against him, takes the only job he can get - to circumnavigate the globe to test a new plane. Crashing in a volcanic garden on an uncharted island over the arctic, he encounters a tribe of Vikings who ride giant eagles, treacherous prehistoric creatures and a secret Nazi airbase. When the Nazis attack America, the humiliated pilot bravely sets out with a small ragtag group to save his country. FIVE OUT OF FIVE STARS! "Wonderful story. War Eagles is a really good adventure story." amazon reader "WW2 with a dash of fantasy! I really enjoyed stepping back in time as the race for air travel was developing. One could truly feel the passion these pilots and engineers had for these magnificent machines. The twist of stepping back into a land of Vikings and dinosaurs was very well executed." amazon reader Inspired by a concept by Merian C. Cooper - the creator of King Kong.Just prior to the start of WWII a publicly humiliated Army Air Corps test pilot, court-martialed for an unauthorized flight that endangered the life of President Roosevelt, takes the only job he can get - flying an experimental airplane around the world from South to North poles. When his plane is attacked and crashes in the Arctic, he finds himself in an undiscovered land inhabited by a lost tribe of Norsemen who ride giant eagles and, in a surprising turn of events, becomes America's only hope against a devastating sneak attack by the Nazis and their powerful new electromagnetic weapon. Review excerpt: "... Debbie Bishop and Carl Macek 's War Eagles delivers a pulse-pounding adventure that blends historical fiction, fantasy, and aerial combat into an exhilarating story. The novel introduces us to court-martialed test pilot Court Bannister, who finds himself thrust into a lost world teeming with Viking warriors riding giant eagles and prehistoric beasts. From the moment his experimental aircraft is attacked over the Arctic, the story launches into a gripping tale of survival, discovery, and redemption. Bishop’s vivid descriptions of aerial maneuvers and intense dogfights immediately immerse the reader in the action, making the high-stakes battles feel incredibly real. What makes War Eagles so captivating is its seamless fusion of historical elements with fantastical concepts. The world-building is particularly strong, as Bishop and Macek bring to life an ancient civilization that has thrived in isolation for centuries, untouched by modern warfare."

But it had other ideas . . . and we never stood a chance. Years later, Jeremiah is the only one standing in the way of human extinction. Pursued by an army of cybernetic warriors and genetically altered hybrids fashioned after mythological creatures, Jeremiah and Gabrielle, a sixteen-year-old child of the apocalypse, must escape through the tangled, backcountry of western North Carolina to rally the remnants of humanity in a desperate final bid to end Archi’s terror reign.

Libet’s trip to Colony Arroyo to visit a mother she’s never known, becomes a transformative adventure of personal growth, societal upheaval and awe-inspiring scientific discovery. She is challenged with a brain injury that causes seizures and memory loss; must learn to travel through the giant javali trees in order to hide from the authorities; and immediately falls under the spell of the floating invertebrates her father called the “liminalis.” In defiance of her powerful Mother who considers the liminalis to be dangerous, Libet sides with and rallies a group of outcasts to change the status quo and protect these unique, fascinating creatures from the threat of extinction by the dictatorial government. In the process of laying bare secrets and lies about the native species, Libet gradually, and somewhat mysteriously, recovers her health while uncovering the reasons her father left the colony with her 25 years earlier and—extraordinarily—why he was never forgotten by the highly intelligent and empathic liminalis. If you love animals, you will love this story. The Liminalis falls on the spectrum of "extremely satisfying stories featuring charming aliens" somewhere between Remarkably Bright Creatures and Project Hail Mary. Get to know the liminalis!
