Sci-Fi with a Slant - Galaxy Cruise by Marcus Alexander Hart #SciFi #Speculative #BookFair

A strange sci-fi comedy. Not quite space opera, and definitely not military science fiction. But it is funny, in a Futurama meets the Love Boat kind of way. And it has a sweet-clean lesbian romance as its B story.

Sci-Fi with a Slant – Cyber Fighter by William Joseph Hill #SciFi #Speculative #BookFair

Kayelle Allen

Sci-Fi with a Slant - Cyber Fighter by William Joseph Hill #SciFi #Speculative #BookFair

A hero's journey in the vein of Star Wars, without the spaceships...

A kind-of "Marvel-esque" origin story of a new type of superhero...

What if you could instantly get expert fighting skills downloaded directly to your brain?

Matrix meets Die Hard and the action keeps going

Cyber Fighter metaphorically explores the over-reliance of technology to acquire knowledge and skills. The idea that you can download mastery directly to your brain (like an app) without putting in the work, and the weaponization of that technology, creating a new worldwide threat. With how we are all connected digitally over the internet and social media, what if you could take that tech and apply it to real life? The book merges sci-fi elements with the martial arts, using familiar tropes and humor to create a fun adventure. It's part kung-fu movie, with the flavor of a spy thriller with a dash of cyberpunk. Favorite genres blended into a melting pot. This novel is based on a feature film script being developed into a movie.

Sci-Fi with a Slant – The Problem with Uncle Teddy’s Memoir by Ed Charlton #SciFi #Speculative #BookFair

Kayelle Allen

The Problem with Uncle Teddy's Memoir

This is officially an "epistolary novel," made of letters, email, office notes, as well as the manuscript pages of the memoir. It's not usually the way sci-fi stories are told (though the original Dracula was!). The memoir has the point of view of the titular alien, but the interleaving pages concern how two human friends deal with the memoir and the uncomfortable memories it stirs up. Originally written as a standalone novel, The Problem with Uncle Teddy's Memoir became the first volume of The Aleronde Trilogy, simply because the characters wouldn't leave me alone.

Sci-Fi with a Slant – The Anchor of Time by Tina Capricorn @tinasammich #SciFi #Speculative #BookFair

Kayelle Allen

The Anchor of Time

The Anchor of Time definitely has some fresh takes on old tropes. For one, the 'chosen one' main heroine is a hair stylist, and I for one have not read a lot of fantasy and sci-fi with a time traveling hair stylist. There is a psychic Tardigrade that changes appearances depending on who it has a psychic link with (their appearance is just a projection of what you want to see), and there is also a sentient quantum computer. Combined with dimensional shift in every chapter, as well the end is also the beginning because the story is told in a time loop.

More wolf than man, Mongrel lives on the fringes. Read Mongrel by Lee Colgin @LeeColgin #SciFi #PNR

Kayelle Allen

More wolf than man, Mongrel lives on the fringes. Read Mongrel by Lee Colgin @LeeColgin #SciFi #PNR

Mongrel, a creature more wolf than man, leads a lonely life on the fringes of pack society—until the night a handsome vampire shows up with a mysterious request.

Bowie, a vampire cursed to a life of endless nights, maintains close ties with his human family. When young girls in their village go missing, he must act quickly.

But to find them, he'll need to convince the local werewolf pack to loan him their best tracker—a wolf known as the Mongrel.

Though he hates the slur, Andras is used to being called Mongrel.

When Bowie refuses to refer to him by anything but his given name, Andras can't help a flicker of unexpected trust toward the stranger.

He volunteers to help Bowie, risking banishment.

Can two tenderhearted men overcome their traumatic pasts and work together to rescue the girls before it's too late? Or will the world's most prolific killer snuff the flames of their passion along with the lives of the captives?

Mongrel by Lee Colgin

This steamy love story spans the country of Hungary as Andras and Bowie journey through cities and wilderness on their quest to right a villain's wicked wrongs. Mongrel features a sweetly possessive werewolf, a cinnamon roll of a vampire, and the worst killer in history. A surprisingly fluffy MM Paranormal/Historical Romance considering the subject matter.

HEA guaranteed with loads of laughs along the way and no cliffhanger ending.

Available on Amazon
