Summary: It started with the insects. The mass die-offs had been a warning unheeded. Before society realized the danger, the Earth had inexorably begun a transformation into a place where life could not survive. A small group found shelter in the Arc, an underground refuge safe from the toxins ravaging the surface. After centuries of darkness, humanity’s second chance is running out—and Raven Wilder knows it. Her job fixing the machinery in the Arc makes her aware of how close everything is to breaking down. When the systems fail, the last survivors of the human race will suffocate in the tunnels meant to protect them from the deadly air outside—starting with the most vulnerable. Unfortunately, in an example of history repeating itself, those in charge dismiss her concerns. When her six-year-old begins showing signs of oxygen deprivation, Raven refuses to go quietly into oblivion. She will break every rule to keep her daughter alive.

Summary: What would you do if you let slip information that could start a war? What if the person you divulged said information to is a rebel queen with a thirst for blood? In a world where metal is rare, you probably wouldn’t make matters worse by revealing a map showing the location of the hoard of steel you just told her about. Steel she could turn into swords, spears, and axes. Steel that will destroy her foes with their pathetic hardened glass weapons and leather armour. Unfortunately, Drome isn’t the most gifted of people when it comes to discretion. Or thinking things through. The consequences hurl him down a path riddled with folk keen to boil him alive, stick pointy objects in his tender flesh or blow him into tiny pieces. With the real queen gunning for him too, Drome reluctantly embarks on a secret mission to fix the mess he started. The civilised world depends on him. All he has to do is end a savage war. With a princess and a sorcerer on his side, what could possibly go wrong? If you like Terry Pratchett, Douglas Adams, and Joe Abercrombie, you won't be able to put down the addictive Hollow series.

Summary: In the year 2069, humanity’s last chance for peace is the first ever interstellar mission. A multi-national crew of the most talented scientists and pilots has been chosen based on their expertise and skill. The final spot aboard the craft is assigned as a prize in a global “BerthRight” lottery, and Leif Grettison is the “everyman volunteer” who won. However, Leif isn’t really an “everyman.” He’s a helicopter paramedic, a lab tech and a former army ranger who fought in The Troubles – a decade plus war that brought the world to the brink of apocalypse. He’s the perfect brawn to the brains aboard the ship and quickly finds himself playing the role of security and handyman as the crew begins to fragment and divide by country, just as they had during the war. Little is known about the world circling the distant star that is the target for the voyage and the journey will take almost fourteen years, Earth-time, each way. To deal with the unexpected, the crew has the finest equipment and the planners believe they have thought of everything. However, when you believe you have thought of everything, the universe has a way of showing that you haven’t. What do you do when it goes wrong, when you can’t call for help, and when adventure leads to deaths?

Forced to go undercover at the Chancellor’s Estate, Todd and Nick discover an ancient and deadly creature preying on residents of the estate. The same creature that is radically effecting Chancellor Shaffer. A creature only Nick can see in its true form. It hunts using specialized skills and has Todd and Nick in its crosshairs.

A scientist with a PhD in ichthyology and a dedication to learning all he can about lungfish, whose existence dates back to the Devonian era, David is determined to see what the Amazon holds.

Summary: When one society fell, assaulted by natural disaster, in its place rose another, molded into something entirely different. Protectorates were divided by beliefs and distance. Slavery was accepted and threats both natural and supernatural were commonplace. This became a world where sentries were needed. Trained almost from infanthood, these tough men and women lived in a society within a society. They were warriors and protectors, ferreting out evil and defending the citizens of New Colorado Protectorate from inhuman terrors and, on occasion, human ones. Todd Ruger was born into life as a sentry. Raised by a hard father into a hard life, Todd becomes the consummate sentry, tough, dangerous, and good at what he does. When he wasn't quite into his teen years, he was bonded to a special young slave named Nick. For years their only interaction was through letters. Friendship turned to a sort of courtship between them. Todd lived for the day Nick became of age and Todd's ownership would take effect. That was the day Nick would leave the village with Todd. They'd begin a life together. They'd make a difference. Raised as a slave, Nick never wanted to be special, but nature had other ideas for him. He grew up in a village with other slave children and was taught to be useful to his future master because he a gift ... or curse. The tutors responsible for his upbringing didn't understand what Nick could do, what he was; they were afraid of him. If sentries hadn't bought him, it was likely he'd never have lived to see the age of five. All that changes the day Nick leaves the village with Todd. He's cared for and shown a new, better life with a man who loves him honestly and wholly. But after being together barely a day, Nick is brutally attacked and injured. Though he recovers without incident, Todd's heart fills with revenge. The guardian in him turns into a dangerous, driven assassin, a wolf on the hunt. Todd's obsession with tracking down the men who hurt Nick and making them pay could very well get them both killed. Can they survive and build the life together they've both dreamed of for years? NOTE: This is the third edition of Marked Yours. The first and second editions were released by another publishing house. This story has been revised and re-edited with the end result being a better, stronger story.
